最后一题通过了 77.77%，不知道错在哪里了 ``` #include <iostream> #include <map> using namespace std; map<long long int, int> ma; int solve(long long int n) {     if (n == 0LL) return 0;     if (n == 1LL) return 1;     if (ma[n] != 0) return ma[n];     if (n % 2 == 1) {         int ans = solve((n-1) / 2) + solve((n-1) / 2 + 1);         ma[n] = ans;         return ans;     } else {         int ans = solve(n / 2);         ma[n] = ans;         return ans;     } } int main() {     long long int n;     while(cin >> n) {         cout << solve(n+1) << endl;     }     return 0; } ```
