## Discussion of Problem 1149. Sinus Dances

I have stupid WA2??? Can you give me some tests?
Posted by Alibi 13 Nov 2015 09:19
Here is my code:
# include <bits/stdc++.h>

using namespace std;

string s[300];

string conv(int x) {
string str;
while(x) {
str.push_back(x % 10 + '0');
x /= 20;
}
reverse(str.begin(), str.end());
return str;
}

int main() {
int n;
cin >> n;
for(int i = 1; i <= n; i++) {
for(int j = 1; j <= i; j++) {
s[i] += "sin(" + conv(j);
if(j != i) {
if(j % 2)
s[i].push_back('-');
else
s[i].push_back('+');
}
}
for(int j = 1; j <= i; j++)
s[i].push_back(')');
}

for(int i = 1; i < n; i++) cout << '(';
for(int i = 1; i <= n; i++) {
cout << s[i] << '+' << n - i + 1;
if(i != n)
cout << ')';
}
cout << endl;
return 0;
}

Here you go.
