If key = middle … WebHere's the pseudocode for binary search, modified for searching in an array. The inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1. Compute guess as the average of max and min, rounded down (so that it is ...
WebFeb 26, 2015 · Also to do a binary search you need to sort your array ex int [] array = {1,2,3,4,5,6,7,8,9,10}; What a binary search does is it looks at the middle element in the array and tests to see if the element is greater or less than the key.
