Question

Given this implementation of insertion sort as seen in the photo below,

What is the worst-case time complexity of this implementation? and why? kindly explain and/or provide examples.

def insertion_sort(arr): for i in range(1, len(arr)): t - arr[i] # get index of arr[i] in # assumed sorted sub-array arr[:i] j = binary_search(arr[i], arr[:i]) # insert arr[i] at index j arr.insert(j, arr[i]) # Removes element at index i + 1 # (shifted because of insert) arr.pop(i+1)
