WebMar 29, 2024 · We can use binary search to reduce the number of comparisons in normal insertion sort. Binary Insertion Sort find use binary search to find the proper location to insert the selected item at each iteration. In normal insertion, sort it takes O (i) (at ith iteration) in worst case. we can reduce it to O (logi) by using binary search. Python WebIf you really wanted to use a for-loop, you could, but the indices guessed by binary search don't go in the sequential order that a for-loop makes convenient. First we might guess the index 12, and then 18, based on some computations. So a while-loop is the better choice.
