WebApr 10, 2024 · So i am trying to write the program of finding if a element is present in a 2D array or not using binary search.I have taken a simple sorted array as test case. for any value of target which is even present in the 2D array it is prompting that element is not found i.e. my binary search function is always returning 0. In computer science, binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array.
