answer
#include <cstdio>
#include <algorithm>
using namespace std;
typedef long long LL;
#define N 100000 + 5
int n, A[N];
int main()
{
scanf("%d", &n);
for (int i = 1; i <= n; i ++)
scanf("%d", A + i);
for (int i = 1, last = 0; i <= n; i ++)
{
if (A[i] != 0)
putchar(A[i] > 0 ? '+' : '-');
else if (A[i] == 0)
putchar(last ? '+' : '0');
if (A[i] >= 0)
{
A[i + 1] += A[i] >> 1;
A[i] &= 1;
}
else
{
int d = (1 - A[i]) / 2;
A[i + 1] -= d;
A[i] += 2 * d;
}
if (A[i] == 1)
last = i;
else while (A[i]) ;
}
puts("");
return 0;
}
这程序好像有点Bug，我给组数据试试？
