Description

Given a two-dimensional array of size R _x 5 (1 < R < 100).

We want to sort the two dimensional array according to each row.

For example:

After sorted

Note that

1.      This problem involves three files.

• function.h: Function definition of sortArray.
• function.c: Function implementation of sortArray.
• main.c: A driver program to test your implementation.

You will be provided with main.c and function.h, and asked to implement function.c.

2.     For OJ submission:

        Step 1. Submit only your function.c into the submission block. (Please choose c compiler) 

        Step 2. Check the results and debug your program if necessary.

Hints : bubble sort algorithm

/* Using bubble sort to rearrange an array A[n] */

for (i = n; i > 0; i--) {

   for (j = 1; j < i; j++) {

      if (A[j-1] > A[j]) {

         /* swap A[j-1] A[j] */

      }

   }

}

function.h

#ifndef FUNCTION_H #define FUNCTION_H #define COLUMN 5 void sortArray(int R, int (*array)[COLUMN]); #endif

main.c

#include <stdio.h> #include <stdlib.h> #include "function.h" int main(void) { int i,j,n,N,R; scanf("%d", &N); int (*array)[COLUMN]; // array is a pointer to an one-dimensional array of COLUMN elements for(n=0;n<N;n++){ scanf("%d", &R); array = (int(*)[COLUMN])malloc(sizeof(int)*COLUMN*R); for(i = 0; i < R; i++) for(j = 0; j < COLUMN; j++) scanf("%d", &array[i][j]); sortArray(R, array); for(i = 0; i < R; i++){ printf("%d", array[i][0]); for(j = 1; j < COLUMN; j++){ printf(" %d", array[i][j]); } printf("\n"); } if(n!=N-1) printf("\n"); free(array); } return 0; }

Input

The first line has an integer N(1<=N<=5000), which means the number of test cases.

For each case, the first line has an integer R (1<R<100) represent the numbers of rows. The following R lines, each containing 5 integers, specify the elements of the two-dimensional array.

Output

Print out all elements of the sorted array row-by-row.

All of the integers in the same line are separated by a space and there is a '\n' at the end of each line. All of the arrays should be separated by a new line character (\n).
