2)Given an n x n matrix, where every row and column is sorted in increasing order. Given a number x, how to decide whether this x is in the matrix. The designed algorithm should have linear time complexity. a) Start with top right element b) Loop: compare this element e with x i) if they are equal then return its position ii) e < x then move it to down (if out of bound of matrix then breakreturn false) iii) e > x then move it to left (if out of bound of matrix then break return false) c) repeat the i), ii) and iii) till you find element or returned false
