Ques link: To and Fro
My code works for the given test cases and on my own test cases,but shows runtime error on submission.Please help.
My code:
#include <iostream>
#include <string.h>
using namespace std;
int main()
{
int n;
cin >> n;
while (n != 0)
{
string s;
cin >> s;
char a[10][20];
int cols = n, rows = s.length() / n, k = -1;
for (int i = 0; i < rows; i++)
{
if (i % 2 == 0)
{
for (int j = 0; j < cols; j++)
{
k++;
a[i][j] = s[k];
}
}
else
{
for (int j = cols - 1; j >= 0; j--)
{
k++;
a[i][j] = s[k];
}
}
}
for (int j = 0; j < cols; j++)
{
for (int i = 0; i < rows; i++)
{
cout << a[i][j];
}
}
cout << endl;
cin >> n;
}
return 0;
}
