WebImplement linear search. Given an array, search key in the array. If key not found print "-1", otherwise print the index of the array. Input Format First line of input contains two integers N and K. N is the size of array and K is the key. Second line contains array elements. Constraints 1 <= N <= 102 0 <= ar [i] <= 109 Output Format WebBinary search is used to search a key element from multiple elements. Binary search is faster than linear search.
