Given a 2D matrix, write code to traverse the matrix in spiral format (clockwise, starting from the top-left).
Example:
Input (5 rows x 4 cols):
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
17 18 19 20
Output: 1 2 3 4 8 12 16 20 19 18 17 13 9 5 6 7 11 15 14 10
Given two numbers, number1 and number2, check the number of borrow operations needed when subtracting number1 from number2. If subtraction is not possible, return "Not possible".
Example:
Input: number1 = 754658, number2 = 2654666
Output: 2
Given a string where multiple characters are repeated consecutively, reduce the size of the string using run-length encoding logic.
Example:
Input: aabbbbeeeeffggg
Output: a2b4e4f2g3
Given a string, its length, and a character c, replace all occurrences of c in the string and capitalize or decapitalize it based on the character's case.
