Description

Given a sequence of  2-digit numbers, use ‘qsort’ to sort the numbers in the following rule:
1. First, sort the numbers by tens digit in increasing order. E.g., 10 is prior to 20.
2. If numbers have the same tens digit, sort them by units digit in decreasing order. E.g., 39 is prior to 38.

Hint:

#include 
#include 
#define SIZE 10
#define LENGTH 2

int comp_func(const void *a, const void *b)
{
    /* your code here */
}

int main()
{
    int i, N;
    int num[SIZE][LENGTH];
    int *ptr[SIZE];
    char str[LENGTH+1];

    scanf("%d", &N);
    for (i=0; i
