Webint binarySearch(int[] A, int x) { int low = 0, high = A.length - 1; while (low <= high) { int mid = (low + high) / 2; if (x == A[mid]) { return mid; } else if (x < A[mid]) { high = mid - 1; } else { low = mid + 1; } } return -1; } Let us get started with the mathematical analysis of Binary Search. Best Case Time Complexity of Binary Search WebThe worst-case running time for binary search is log (n). Recall: if f (n) is O (g (n)) this means that f (n) grows asymptotically no faster than g (n) if f (n) is Ω (g (n)) this means that f (n) grows asymptotically no slower than g (n) if f (n) is Θ (g (n)) this means that f (n) grows asymptotically at the same rate as g (n) As a result:

WebLinear Search Binary Search Resources What is Big O Notation? Big O notation is used used as a tool to describe the growth rate of a function in terms of the number of instructions that need to be processed (time complexity) or the … WebLet min = 0 and max = n-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! Return guess. If the guess was too low, that is, array [guess] < target, then set min = guess + 1. Otherwise, the guess was too high. Set max = guess - 1. Go back to step 2.
