WebBinary search via iteration. Suppose we want to find an element in a sorted array. We can do much better than scanning from left to right: we can use binary search. Here is the binary search algorithm, written as a loop. binary_search.java. Conceptually, this algorithm is simple. But it is deceptively tricky to get exactly right. WebConcept of Linear Search. Let's understand the following steps to find the element key = 7 in the given list. Step - 1: Start the search from the first element and Check key = 7 with each element of list x. Step - 2: If element is found, return the index position of the key. Step - 3: If element is not found, return element is not present.
