WebBinary search is a classic algorithm in computer science. It often comes up in programming contests and technical interviews. Implementing binary search turns out to be a challenging task, even when you understand … WebNote two interesting functions in C++: lower_bound and upper_bound, you should check them even if you don't know any C++. ... Let's implement our own version of lower and upper bounds to practice binary search: // returns index of the smallest element in the list bigger than or equal to target, // or -1 if there is no such element. int ... WebHere is modified pseudocode for binary search that handles the case in which the target number is not present: Let min = 0 and max = n-1. If max < min, then stop: target is not present in array. Return -1. Compute guess as the average of max and min, rounded down (so that it is an integer). If array [guess] equals target, then stop. You found it! class 10 his ch 1 summary

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)
