输入一组整数（可以有重复数据），求第二大的值 - 编程论坛

奇怪的题目，如果输入的值一样大，怎么办？

程序代码：

#include <stdio.h>
#include <limits.h>

int main( void )
{
    unsigned n;
    scanf( "%u", &n );

    int first = INT_MIN;
    int second = INT_MIN;
    for( unsigned i=0; i!=n; ++i )
    {
        int value;
        scanf( "%d", &value );

        if( value > first )
        {
            second = first;
            first = value;
        }
        else if( value!=first && value>second )
        {
            second = value;
        }
    }

    printf( "%d", second );
}

/*数组不用排序思想*/
#include <stdio.h>
int main()
{
    int a[21];
    int n, max = 0, min = 1000, sub = 0;
    int temp = 0;
    scanf("%d", &n);
    for (int i = 0; i < n; i++)
    {
        scanf("%d", &a[i]);
        if (a[i] > max) max = a[i];
    }
    for (int i = 0; i < n; i++)
    {
        sub = max - a[i];
        if (sub && sub < min)
        {
            min = sub;
            temp = a[i];
        }
    }
    printf("%d\n", temp);
    return 0;
}
