    You are given an integer array nums and an integer k.

    + +

    An integer h is called valid if all values in the array that are strictly greater than h are identical.

    + +

    For example, if nums = [10, 8, 10, 8], a valid integer is h = 9 because all nums[i] > 9 are equal to 10, but 5 is not a valid integer.

    + +

    You are allowed to perform the following operation on nums:

    + +
      +
    • Select an integer h that is valid for the current values in nums.
    • +
    • For each index i where nums[i] > h, set nums[i] to h.
    • +
    + +

    Return the minimum number of operations required to make every element in nums equal to k. If it is impossible to make all elements equal to k, return -1.

    + +

     

    +

    Example 1:

    + +
    +

    Input: nums = [5,2,5,4,5], k = 2

    + +

    Output: 2

    + +

    Explanation:

    + +

    The operations can be performed in order using valid integers 4 and then 2.

    +
    + +

    Example 2:

    + +
    +

    Input: nums = [2,1,2], k = 2

    + +

    Output: -1

    + +

    Explanation:

    + +

    It is impossible to make all the values equal to 2.

    +
    + +

    Example 3:

    + +
    +

    Input: nums = [9,7,5,3], k = 1

    + +

    Output: 4

    + +

    Explanation:

    + +

    The operations can be performed using valid integers in the order 7, 5, 3, and 1.

    Bob is stuck in a dungeon and must break n locks, each requiring some amount of energy to break. The required energy for each lock is stored in an array called strength where strength[i] indicates the energy needed to break the ith lock.

    + +

    To break a lock, Bob uses a sword with the following characteristics:

    + +
      +
    • The initial energy of the sword is 0.
    • +
    • The initial factor X by which the energy of the sword increases is 1.
    • +
    • Every minute, the energy of the sword increases by the current factor X.
    • +
    • To break the ith lock, the energy of the sword must reach at least strength[i].
    • +
    • After breaking a lock, the energy of the sword resets to 0, and the factor X increases by a given value K.
    • +
    + +

    Your task is to determine the minimum time in minutes required for Bob to break all n locks and escape the dungeon.

    + +

    Return the minimum time required for Bob to break all n locks.

    You are given two integers n and m that consist of the same number of digits.

    + +

    You can perform the following operations any number of times:

    + +
      +
    • Choose any digit from n that is not 9 and increase it by 1.
    • +
    • Choose any digit from n that is not 0 and decrease it by 1.
    • +
    + +

    The integer n must not be a prime number at any point, including its original value and after each operation.

    + +

    The cost of a transformation is the sum of all values that n takes throughout the operations performed.

    + +

    Return the minimum cost to transform n into m. If it is impossible, return -1.

    + +

    A prime number is a natural number greater than 1 with only two factors, 1 and itself.

    Example 1:

    + +
    +

    Input: n = 10, m = 12

    + +

    Output: 85

    + +

    Explanation:

    + +

    We perform the following operations:

    + +
      +
    • Increase the first digit, now n = 20.
    • +
    • Increase the second digit, now n = 21.
    • +
    • Increase the second digit, now n = 22.
    • +
    • Decrease the first digit, now n = 12.
    • +
    +
    + +

    Example 2:

    + +
    +

    Input: n = 4, m = 8

    + +

    Output: -1

    + +

    Explanation:

    + +

    It is impossible to make n equal to m.

    +
    + +

    Example 3:

    + +
    +

    Input: n = 6, m = 2

    + +

    Output: -1

    + +

    Explanation: 

    + +

    Since 2 is already a prime, we can't make n equal to m.

    +
    + +

     

    +

    Constraints:

    + +
      +
    • 1 <= n, m < 104
    • +
    • n and m consist of the same number of digits.

    You are given an integer array nums that represents a circular array. Your task is to create a new array result of the same size, following these rules:

    +For each index i (where 0 <= i < nums.length), perform the following independent actions: + +
      +
    • If nums[i] > 0: Start at index i and move nums[i] steps to the right in the circular array. Set result[i] to the value of the index where you land.
    • +
    • If nums[i] < 0: Start at index i and move abs(nums[i]) steps to the left in the circular array. Set result[i] to the value of the index where you land.
    • +
    • If nums[i] == 0: Set result[i] to nums[i].
    • +
    + +

    Return the new array result.

    + +

    Note: Since nums is circular, moving past the last element wraps around to the beginning, and moving before the first element wraps back to the end.

    + +

     

    +

    Example 1:

    + +
    +

    Input: nums = [3,-2,1,1]

    + +

    Output: [1,1,1,3]

    + +

    Explanation:

    + +
      +
    • For nums[0] that is equal to 3, If we move 3 steps to right, we reach nums[3]. So result[0] should be 1.
    • +
    • For nums[1] that is equal to -2, If we move 2 steps to left, we reach nums[3]. So result[1] should be 1.
    • +
    • For nums[2] that is equal to 1, If we move 1 step to right, we reach nums[3]. So result[2] should be 1.
    • +
    • For nums[3] that is equal to 1, If we move 1 step to right, we reach nums[0]. So result[3] should be 3.
    • +
    +
    + +

    Example 2:

    + +
    +

    Input: nums = [-1,4,-1]

    + +

    Output: [-1,-1,4]

    + +

    Explanation:

    + +
      +
    • For nums[0] that is equal to -1, If we move 1 step to left, we reach nums[2]. So result[0] should be -1.
    • +
    • For nums[1] that is equal to 4, If we move 4 steps to right, we reach nums[2]. So result[1] should be -1.
    • +
    • For nums[2] that is equal to -1, If we move 1 step to left, we reach nums[1]. So result[2] should be 4.

    You are given an array points where points[i] = [xi, yi] represents the coordinates of a point on an infinite plane.

    + +

    Your task is to find the maximum area of a rectangle that:

    + +
      +
    • Can be formed using four of these points as its corners.
    • +
    • Does not contain any other point inside or on its border.
    • +
    • Has its edges parallel to the axes.
    • +
    + +

    Return the maximum area that you can obtain or -1 if no such rectangle is possible.

    + +

     

    +

    Example 1:

    + +
    +

    Input: points = [[1,1],[1,3],[3,1],[3,3]]

    + +

    Output: 4

    + +

    Explanation:

    + +

    Example 1 diagram

    + +

    We can make a rectangle with these 4 points as corners and there is no other point that lies inside or on the border. Hence, the maximum possible area would be 4.

    +
    + +

    Example 2:

    + +
    +

    Input: points = [[1,1],[1,3],[3,1],[3,3],[2,2]]

    + +

    Output: -1

    + +

    Explanation:

    + +

    Example 2 diagram

    + +

    There is only one rectangle possible is with points [1,1], [1,3], [3,1] and [3,3] but [2,2] will always lie inside it. Hence, returning -1.

    +
    + +

    Example 3:

    + +
    +

    Input: points = [[1,1],[1,3],[3,1],[3,3],[1,2],[3,2]]

    + +

    Output: 2

    + +

    Explanation:

    + +

    Example 3 diagram

    + +

    The maximum area rectangle is formed by the points [1,3], [1,2], [3,2], [3,3], which has an area of 2. Additionally, the points [1,1], [1,2], [3,1], [3,2] also form a valid rectangle with the same area.

    There are n points on an infinite plane. You are given two integer arrays xCoord and yCoord where (xCoord[i], yCoord[i]) represents the coordinates of the ith point.

    + +

    Your task is to find the maximum area of a rectangle that:

    + +
      +
    • Can be formed using four of these points as its corners.
    • +
    • Does not contain any other point inside or on its border.
    • +
    • Has its edges parallel to the axes.
    • +
    + +

    Return the maximum area that you can obtain or -1 if no such rectangle is possible.

    + +

     

    +

    Example 1:

    + +
    +

    Input: xCoord = [1,1,3,3], yCoord = [1,3,1,3]

    + +

    Output: 4

    + +

    Explanation:

    + +

    Example 1 diagram

    + +

    We can make a rectangle with these 4 points as corners and there is no other point that lies inside or on the border. Hence, the maximum possible area would be 4.

    +
    + +

    Example 2:

    + +
    +

    Input: xCoord = [1,1,3,3,2], yCoord = [1,3,1,3,2]

    + +

    Output: -1

    + +

    Explanation:

    + +

    Example 2 diagram

    + +

    There is only one rectangle possible is with points [1,1], [1,3], [3,1] and [3,3] but [2,2] will always lie inside it. Hence, returning -1.

    +
    + +

    Example 3:

    + +
    +

    Input: xCoord = [1,1,3,3,1,3], yCoord = [1,3,1,3,2,2]

    + +

    Output: 2

    + +

    Explanation:

    + +

    Example 3 diagram

    + +

    The maximum area rectangle is formed by the points [1,3], [1,2], [3,2], [3,3], which has an area of 2. Additionally, the points [1,1], [1,2], [3,1], [3,2] also form a valid rectangle with the same area.

    +
