CHEWBACCA AND NUMBER two testcases showing no output

#1

the code is running fine upto number 10^18 whats the problem in the code ?
code link :https://ide.codingblocks.com/s/100034

#2

Read the question carefully u have to print the minimum not maximum and also the if condition is wrong

#3

@phantom hi , i used 9-a[i] for a[i]>4 that means for 5,6,7,8 i want to print 4,3,2,1 , that seems okay and for the if a[i]==0 or a[i]==9 then it will invert it to 0 which we have to ignore acc to the prob , pls help i didnt get it .

#4

in line 25 u have write
if(A[0]==9 || A[0]==0) {
return 0 ;
}
id ex=9562 then u r always returning 0 as A[0] is always 9

#5

@phantom cuz the condition suggests that the no shouldnt start with 0

#6

if a[0]0==9 then also ur code will not work as u have return if a[0]==9 || a[0]==0 return0;

#7

cuz after inverting it will become 0 that is not acceptable

#8

when u write return 0 that means u r terminating the program

#9

The decimal representation of the final number shouldn’t start with a zero. if the first digit is 0 then close the program , thats what i hv done , pls help , iam not getting it …

#10

u have also close the programe if a[0]==9
check for an exmaple starting with digit 9

#11

can u pls modify my code … ?

#12

check this

#13

thanks , i hope this works for me

#14

it is opening for me

#15

did u get ur error point

#include<bits/stdc++.h>
using namespace std;
int main()
{

string num;
cin>>num;
for(int i=num.length()-1;i>=0;i--)
{	string temp=num;
	char m=num[i];
	char n='9';
	if(m>4)
	num[i]=n-num[i]+48;
	
	if(num>temp)
		num[i]=m;

}
cout<<num;
}
my two test cases are not running
