WebFeb 9, 2024 · Binary Search is a searching technique which works on the Divide and Conquer approach. It is used to search for any element in a sorted array. Compared with linear, binary search is much faster with a Time Complexity of O (logN), whereas linear search works in O (N) time complexity. WebFirst we specify the case (worst,best, average, etc.) and then we specify O, Ω (upper bound, lower bound) or Θ (tight bounds). For Binary search: In the best case scenario (our initial guess finds the target value): - binary search is Θ (1) and as a result is also Ω (1) and O (1). In the worst case scenario (our target is not in the array) WebActually i did a two function to find the numbers where it is locating for lower and upper bound. int binarylower(int a[],int m,int l,int u) { int mid,c=0; if(l<=u) { mid=(l+u)/2; … dickey home inspection
