Can you please give me your submission link or your code so I can see what is wrong.

@sarthak1308 Your Code:

#include<iostream>
using namespace std;
int main()
{
	int t;
	cin>>t;
	if((t>=1)&&(t<=1000))
	{
		for(int i=0; i<t; i++)
		{
		int num,rnum=0;
		cin>>num;
		if((num>=1)&&(num<=100000))
		{
			while(num!=0)
			{
				int b=num%10;
				num=num/10;
				rnum=rnum*10+b;
			}
			cout<<rnum<<endl;
		}
	    }
	}
}

How is it affecting the logic…?
i got your point, it should be that way (more professional but logic…?)

117

Still it is throwing wrong output…

118

This change really shouldn’t make any difference - can you give a testcase where it does?

I can’t see anything wrong with @sarthak1308’s solution at all, provided that the constraints are correct, which they often aren’t.

@sarthak1308 - try removing the if((t>=1)&&(t<=1000)) and if((num>=1)&&(num<=100000)) checks (they are not needed anyway). Then submit, and post a link to your submission here.

@vijju123 / @admin - can we get the constraints/ testcases fixed for this Problem?

Thanks to @aryan12 for confirming :slight_smile:

Gotcha! You have to remove the Constraints part.
Here my solution:

#include<iostream>
using namespace std;
int main()
{
	int t;
	cin>>t;
	if((t>=1)&&(t<=1000))
	{
		for(int i=0; i<t; i++)
		{
		int num,rnum=0;
		cin>>num;
			while(num>=10)
			{
				int b=num%10;
				rnum=rnum*10+b;
				num=num/10;
			}
			rnum=rnum*10+num;
			cout<<rnum<<endl;
		}
	}
}

I don’t know, but I have just removed these two lines and I have got AC

2 lines I have removed

if((t>=1)&&(t<=1000))

if((num>=1)&&(num<=100000))

This gives the wrong answer for the testcase:

9
3 66
3 20
2 60
2 1
1 69
3 66
3 1
3 72
1 54

(the answer should be

2 388
