Sample Input
aba
10
Sample Output
7
Explanation
The first n= 10 letters of the infinite string are abaabaabaa. Because there are 7 a's, we print on a new line.

Second Test case

Sample Input 1
a
1000000000000

Sample Output 1
1000000000000

Explanation 1
Because all of the first n =1000000000000
letters of the infinite string are a, we print 1000000000000 on a new line.
