String

# PROBLEM:

Given a String and a number, shift all characters by the number.

# QUICK EXPLANATION:

Traverse the string replace all alphabets with Char-Num.

# EXPLANATION:

Traverse the String and replace all Aplhabets with char- num and add 26 if it goes below ‘A’ or ‘a’.

# ALTERNATE EXPLANATION:

Substract ‘a’ or ‘A’ to make it out of 26, add (26-num) and mod 26.

# SOLUTIONS:

Setter's Solution
``````#include<bits/stdc++.h>
using namespace std;
#define ll long long int

void solve()
{
ll n,m,x,y,i,j,k;
string s;
getline(cin,s);
getline(cin,s);
cin>>n;
n=n%26;
for(auto ch:s){
if((ch<='z'&&ch>='a')){
char temp=ch-n;
if(temp<'a'){
temp=temp+26;
}
cout<<temp;
}
else if(ch<='Z'&&ch>='A'){
char temp=ch-n;
if(temp<'A'){
temp=temp+26;
}
cout<<temp;
}
else{
cout<<ch;
}
}
}

int main()

ios_base::sync_with_stdio(false);
