最小三个数-题解(C语言描述---附带详细的例子)

代码有点啰嗦。
    int indexMini; // index of current Minimum number
    for (int i = 0; i < 3; i++) // we need only first 3 numbers. Thinking of Selection Sort
    {
        indexMini = i;
        for (int j = i + 1; j < nLength; j++ )
        {
            if (array[j] < array[indexMini]) // Try to find minimum number
             indexMini = j;
        }
        
        swap(&array[i], &array[indexMini]);
        
        if (i == 2)
            printf("%d", array[i]);
        else
            printf("%d ", array[i]);
    }
