c++ - 想要将一组乱序的数排列，在插入一组数，使其变为升序数列。

Question

现在每次输出都会少掉最大项，还会多出来一些0，请问如何解决？

long long int a[1000];

Change the second for in addsort to the following, the logic is wrong, compare the codes yourself

for (i=1;i<=totalnum;i++)
{
    if (aposition > num)
    {
        printf("%lld ",add[addposition]);
        addposition++;
    } else if (addposition > addnum)
    {
        printf("%lld ",a[aposition]);
        aposition++;
    } else if (a[aposition] > add[addposition])
    {
        printf("%lld ",add[addposition]);
        addposition++;

    } else if (a[aposition] == add[addposition])
    {
        printf("%lld %lld ",a[aposition],add[addposition]);
        i++;
        aposition++;
        addposition++;

    } else if (a[aposition] < add[addposition])
    {
        printf("%lld ",a[aposition]);
        aposition++; 
    }
}
