+# Row-Wise Wave Print in a Matrix
+
+## Problem Statement
+Given a 2D matrix of size n x m, print the matrix in a wave-like manner.
+
+## Example
+Given matrix:
+A = [
+    [11, 12, 13, 14]
+    [21, 22, 23, 24]
+    [31, 32, 33, 34]
+    [41, 42, 43, 44]
+]
+
+The wave print output should be:
+11 12 13 14 24 23 22 21 31 32 33 34 44 43 42 41
+
+## Approach
+
+# Input
+A 2D matrix of size n x m where n is the number of rows and m is the number of columns.
+
+# Output
+Single list or sequence of elements representing the matrix in a row-wise wave form.
+
+# Algorithm:
+1. Traverse through the rows one by one.
+2. For each even-indexed row (0, 2, 4,...), print the elements from left to right.
+3. For each odd-indexed row (1, 3, 5,...), print the elements from right to left.
+4. Continue until all rows are processed.

+# Column-Wise Wave Print in a Matrix
+
+## Problem Statement
+Given a 2D matrix of size n x m, print the matrix in a wave-like manner.
+
+## Example
+Given matrix:
+A = [
+    [11, 12, 13, 14]
+    [21, 22, 23, 24]
+    [31, 32, 33, 34]
+    [41, 42, 43, 44]
+]
+
+The wave print output should be:
+11, 21, 31, 41, 42, 32, 22, 12, 13, 23, 33, 43, 44, 34, 24, 14
+
+## Approach
+
+# Input
+A 2D matrix of size n x m where n is the number of rows and m is the number of columns.
+
+# Output
+Single list or sequence of elements representing the matrix in a column-wise wave form.
+
+# Algorithm:
+1. Traverse through the columns one by one.
+2. For each even-indexed row (0, 2, 4,...), print the elements from top to bottom.
+3. For each odd-indexed row (1, 3, 5,...), print the elements from bottom to top.
+4. Continue until all columns are processed.
+
+## Complexity (in both cases)
+1. Time Complexity: O(n * m), where n is the number of rows and m is the number of columns, since we visit each element exactly once.
+2. Space Complexity: O(1), as no extra space is used apart from the input matrix.
