WebBinary search is used because it has a time complexity of O (N) for a sorted array. If we follow sequential access of Linked List, then it will take O (N) time to find the middle element. With this, the overall time complexity of Binary Search on Linked List will become O (N * logN). This will slower than linear search.

WebAug 26, 2024 · Time Complexity Analysis Let us assume that we have an array of length 32. We'll be applying Binary Search to search for a random element in it. At each iteration, the array is halved. Iteration 0: Length of array = 32 Iteration 1: Length of array = 32/2 = 16 Iteration 2: Length of array = 32/2^2 = 8 Iteration 3: Length of array = 32/2^3 = 4 WebComplexity Time complexity: O (log (n)) Code class Solution { public: int search(vector& n, int t) { int ind = lower_bound(n.begin(),n.end() , t) - n.begin(); if(ind < n.size() && n[ind]==t ) return ind; return -1; } }; 6 6 Comments (0) No comments yet.
