Q1. Insertion sort implement in c++
Ans. 
Insertion sort is a simple sorting algorithm that builds the final sorted array one item at a time.
• Start from the second element and compare it with the elements before it to find the correct position.

• Repeat this process for all elements in the array.

• Time complexity is O(n^2) in the worst case scenario.

• Example: void insertionSort(string arr[], int n) { for (int i = 1; i < n; i++) { string key = arr[i]; int j = i - 1; w
