Whats wrong in this code ?--> recursion lexographically

#1

#include <bits/stdc++.h>
using namespace std;
void lexographically(int a,int n){
if(a>n){
return ;
}
cout<<a<<" ";
int i=0;
if(a==0){
i=1;
}
for(;i<n;i++){
lexographically(a*10+i,n);
}
}

int main() {
int n;
cin>>n;

lexographically(0,n);
cout<<endl;
return 0;

}

#2

hi @bhardwajsaksham796,
Similarly Classification acc to the Given prblm :-

  • Bigger Problem : To Print all of the counting from 1 to N.
  • Smaller Problem : Assume the recursion works and will give you ans for counting 2 to N and 3 to N and 4 to N upto 9 to N.
  • Self Work : In order to make you smaller prblm your problem all you need to print your current number and rest will be done by the Smaller work.
