Print Matrix in Spiral Order

Given a 2-dimensional matrix, print the elements in spiral order. We can imagine the spiral traversal as an ordered set of matrix segments with horizontal and vertical boundaries, where both boundaries are reduced by one at each step. This is a good matrix problem to learn problem-solving using iteration and recursion.

Search in a row-wise sorted 2D matrix

You are given a row-wise sorted 2D matrix and a given integer k, write a program to find whether the integer ‘k’ is present in the matrix or not. The matrix has the following properties: Integers in each row are sorted from left to right and the first integer of each row is greater than the last integer of the previous row.
