WebMar 29, 2024 · 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 def binary_search (arr, val, start, end): if start == end: if arr [start] > val: return start WebJan 12, 2024 · While binary trees and linked lists both use pointers to keep track of nodes, binary trees are more efficient for searching. In fact, linked lists are O (n) when used to search for a specific element - that’s pretty bad! Linked lists excel at removing and inserting elements quickly in the middle of the list. ngrok Sponsored
