A string S is passed as the input. A
positive integer X is also passed as the input. The program must print the
characters at positions which are multiples of X.
Input
Format:
The first line contains S. The second line
contains X.
Output
Format:
The first line contains the characters at
positions which are multiples of X.
Boundary
Conditions:
Length of S will be from 3 to 100.
Example
Input/Output 1:
Input:
abcdexyzwqpoolj
5
Output:
eqj
Explanation:
The multiples of 5 are like 5, 10, 15,...
So the characters in these positions are e,q,j
Solution:
s,x=input(),int(input())
print(''.join(s[i] for i in
range(x-1,len(s),x)))
