Merge Sort is a divide and conquer algorithm that divides the input array into two halves, sorts them recursively, and then merges them back together in sorted order.
Divide the input array into two halves
Sort each half recursively
Merge the sorted halves back together in sorted order
Time complexity of O(n log n)
Example: [38, 27, 43, 3, 9, 82, 10] -> [3, 9, 10, 27, 38, 43, 82]

Given an array of integers, find a subarray with a given sum S.
Iterate through the array while keeping track of the current sum and start index.
Use a hashmap to store the sum and its corresponding index.
If the current sum - S is found in the hashmap, a subarray with sum S exists.
Return the start index and current index as the end index.
Given a string S, your task is to recursively remove all consecutive duplicate characters from the string.
String S
Output string
Recursively remove consecutive duplicate characters from a string.
Use recursion to check if the current character is the same as the next character, if so skip the next character
Base case: if string length is 1, return the string
Example: Input: 'aabbc' Output: 'abc'
