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. If they are not equal, the half in which the target cannot lie is eliminated and the search continues on the remaining half, again …

We’ll call the sought value the target value for clarity. Binary search maintains a contiguous subsequence of the starting sequence where the target value is surely located. This is called the search space.
WebBinary search is a method of finding an element in an array by sorting the array and then dividing the array into half, till the number is found. It is a sorting algorithm.
