Recap: Matrix Stats

Combine nested loops, pointers, and pass by reference

Mission: The Memory Tape Diagnostic

A 3x3 block of memory has just been read off a tape. Before you archive it, you need a quick diagnostic: the sum of all cells, the lowest value, and the highest spike. One function must compute all three results at once, through pointers.

  1. Read 9 integers from input, 3 per line across 3 lines, into an array int matrix[3][3]
  2. Write void matrix_stats(int matrix[3][3], int *sum, int *min, int *max) using nested loops to scan the matrix
  3. Set the sum, min, and max values through pointers
  4. Call the function from main and print the results, matching the format in the example exactly

Example

Input

5 12 3
8 1 15
7 9 4

Output

Sum: 64
Min: 1
Max: 15

Example

Input

2 4 6
8 10 12
14 16 18

Output

Sum: 90
Min: 2
Max: 18

The function "returns" three values at once using pointers: the pass-by-reference pattern
