REPLACE THEM ALL

#1

MY TEST CASE 2 IS NOT PASSED

#2

testcase failed because you miss one corner case
what if input is
n = 0
then in that case your output will be 0 but correct output is 5

i hope you understand this point
and also
this portion of your code is useless, i didn’t understand why you have done this

	long long int total = 0;
	while (sum)
	{
		int a = 0;
		a = sum % 10;
		sum = sum / 10;
		total = (total * 10) + a;
	}
	cout << total;

if you didn’t understand feel free to ask

#3

what i am doing is like i am seeing the digits from back and restoring it in a variable so the digit is reversed and now i want to print that in the form which is required that is reason i have applied second loop

#4

see the code which i have one now which is for one zero only and it ran all test cases

#5

you can do it like this

long long int sum = 0;
	int pv = 1;
	while (n)
	{
		int d;
		d = n % 10;
		n = n / 10;
		if (d == 0)
		{
			d = 5;
		}

		sum = sum + d * pv;
		pv = pv * 10;
	}
