Matrix Search

Write an efficient algorithm that searches for a value in an m x n matrix.

This matrix has the following properties:

  1. Integers in each row are sorted from left to right.
  2. The first integer of each row is greater than or equal to the last integer of the previous row.


Consider the following matrix:

  [1,   3,  5,  7],
  [10, 11, 16, 20],
  [23, 30, 34, 50]

Given target = 3, return 1 ( 1 corresponds to true )

Return 0 / 1 ( 0 if the element is not present, 1 if the element is present ) for this problem

NOTE: You only need to implement the given function. Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified. Still have a doubt? Checkout Sample Codes for more details.
