Matrix
Objective
The objective of this problem is to ensure that students know how to use 2
dimensional array and simple looping technique.
Problem Description
Given a 2 dimensional array of size N x M containing 1 or 0 and a query (ROW or
COLUMN), determine the sum of the numbers in the array corresponding to the
query. For example, query “ROW 3” means sum all the elements in the 3rd row of the
array.
Input
The first line of the input contains two integers, N (1 <= N <= 100) and M (1 <= M
<= 100). The next line is an array with size N x M. The next line is the query with
format “ROW x“, (1 <= x <= N) or “COLUMN y”, (1 <= y <= M).
Output
Output the answer to the query.
Sample Input
4 5
1 0 1 0 1
0 1 0 1 0
1 1 1 0 1
0 0 1 0 0
ROW 3
Sample Output
4
Explanation
1 0 1 0 1
0 1 0 1 0
ROW 3 1 1 1 0 1
0 0 1 0 0
The sum of numbers in row 3 is 4
