Sort Sabotage

Description

This Python insertion sort has a bug: it sorts in descending order because < should be >.


def insertion_sort(arr):
    for i in range(1, len(arr)):
        key = arr[i]
        j = i - 1
        while j >= 0 and arr[j] < key:  # BUG: < should be >
            arr[j + 1] = arr[j]
            j -= 1
        arr[j + 1] = key
    return arr

Input: [5, 2, 8, 1, 9, 3]
