Java Exercises: Adds up columns and rows of given table as shown in the specified figure
Java Basic: Exercise-242 with Solution
Your task is to develop a small part of spreadsheet software.
Write a Java program which adds up columns and rows of given table as shown in the specified figure:
Pictorial Presentation:
Input:
n (the size of row and column of the given table)
1st row of the table
2nd row of the table
:
:
n th row of the table
The input ends with a line consisting of a single 0.
Output:
For each dataset, print the table with sum of rows and columns.
Sample Solution:
Java Code:
import java.util.*;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Input number of rows/columns (0 to exit)");
while(true){
int n = sc.nextInt();
if(n==0)break;
int[][] map = new int[n+1][n+1];
for(int i=0;i<n;i++){
for(int j=0;j<n;j++){
map[i][j] = sc.nextInt();
map[i][n] += map[i][j];
}
map[n][n] += map[i][n];
}
for(int i=0;i<n;i++){
for(int j=0;j<n;j++){
map[n][i] += map[j][i];
}
}
System.out.println("Result:");
for(int i=0;i<n+1;i++){
for(int j=0;j<n+1;j++){
System.out.printf("%5d", map[i][j]);
}
System.out.println();
}
}
}
}
Sample Output:
Input number of rows/columns (0 to exit) 4 25 69 51 26 68 35 29 54 54 57 45 63 61 68 47 59 Result: 25 69 51 26 171 68 35 29 54 186 54 57 45 63 219 61 68 47 59 235 208 229 172 202 811
