You are given a sequence of 2626 integers P=(P1,P2, .... p26) consisting of integers from 11 through 2626. It is guaranteed that all elements in PP are distinct. Print a string SS of length 2626 that satisfies the following condition.
For every ii(1 \leq i \leq 26)(1≤i≤26), the ii-th character of SS is the lowercase English letter that comes P_iPi-th in alphabetical order.
Constraints
1 \leq P_i \leq 261≤Pi≤26
P_i \neq P_jPi=Pj(i \neq j)(i=j)
All values in input are integers.
Input
Input is given from Standard Input in the following format: P1,P2, .... p26
