Pattern – Integer to Alphabets

Given a number N, convert the number to character values based on alphabet positions as given in Example Input/Output.

Hint: Use modulo and division operator repeatedly to obtain the pattern.

Boundary Condition(s):
1 <= N <= 10000000

Input Format:
The first line contains N.

Output Format:
The first line contains the string representation.

Example Input/Output 1:
Input:
10

Output:
J

Example Input/Output 2:
Input:
28

Output:
AB

n=int(input())
a="ABCDEFGHIJKLMNOPQRSTUVWXYZ"
s=""
if(n<=26):
    print(a[n-1],end="")
    exit()
while(n>26):
    s+=a[(n%26)-1]
    n//=26
s+=a[n-1]
print(s[::-1])
