HackerEarth ( Problem A ) Pikachu and the Game of Strings problem solution

YASH PAL, 31 July 202411 February 2026
In this HackerEarth (Problem A) Pikachu and the Game of Strings problem solution, Pikachu has recently learnt a new move s. He knows he can work hard and convert it into a stronger move t. Both the moves s and t contain the same number of letters.
In a single day, Pikachu can increase any letter of move s by one, that is, in a single day, he can convert letter A to B, C to D, M to N and so on. He can also convert letter Z to letter A. 
Pikachu just realized he also has a hidden ability. It can help him increase any letter of move s by 13, that is, in a single day, he can convert letter A to letter N, B into O, M into Z, O into B and so on.  
Now Pikachu wants to know the minimum number of days in which he can convert the move s into move t ?

HackerEarth ( Problem A ) Pikachu and the Game of Strings problem solution.

#include <bits/stdc++.h>

using namespace std;

int main(){
int n;
cin>>n;
string s,t;
cin>>s>>t;
int ans=0;
for(int i=0;i<n;i++){
ans+=min((t[i]-s[i]+26)%26,1+(t[i]-(s[i]+13)+52)%26);
}
cout<<ans<<endl;
}

Second solution

n = int(raw_input())
s = raw_input()
t = raw_input()
def f(g):
x = ord(g[0])
y = ord(g[1])
return min((y-x)%26, (y-(x+13)%26)%26 + 1)
print sum(map(f, zip(s,t)))
