It is giving wrong answer

#1

how can i store large integers in an character array

#2

you can simply take a string and input the number as a string,
Code

#3

#include<bits/stdc++.h>
using namespace std;

void chewbacca(char* a,int i,char* out,int j)
{
if(a[i]==’\0’)
{
out[j]=’\0’;
cout<<out<<endl;
return;
}
int ch=a[i]-‘0’;
int d=abs(9-ch);
if(d<ch)
a[i]=d;
else
a[i]=ch;

chewbacca(a,i+1,out,j+1);
return;

}
int main() {
char a[100];
cin>>a;
char out[100];
chewbacca(a,0,out,0);
return 0;
}

#4

This is what i have done

#5

since you are making changes to a, you need to print a only and you need to change the way you were assigning a[i], instead of a[i] = d,. a[i] = d + ‘0’ would come

Corrected Code
