WebMar 15, 2024 · A simple Binary Search Algorithm is as follows: Calculate the mid element of the collection. Compare the key items with the mid element. If key = middle element, then we return the mid index position for the key found. Else If key > mid element, then the key lies in the right half of the collection. Thus repeat steps 1 to 3 on the lower (right ... corehr login dkit
