This program output is showing time limit exceeded.what should i do now?

Question

import java.util.Scanner;
public class Difference{
public static void main(String[] args)
{
int num;
int diff;
int even=0;
int odd=0;
int count=1;
int sum=0;
Scanner input=new Scanner(System.in);
num=input.nextInt();
while(num!=0)
{
sum=num%10;
if(count%2==0)
{
even=sum+even;
}
else
{
odd=odd+sum;
}
num/=10;
count++;
}
diff=odd-even;
System.out.print(diff);
}
}

Answer 1

You seem to have alot of variables thus ur programme is stuck in time complexity

Answer 2

Within your while loop, you seem to have forgotten to change the value of num, which keeps it at whatever value it was initially and never lets the conditional within the loop return false (which is causing the time limit exceeded error). What you could do is include some calculation at the end of your loop to allow the value of num to go down and eventually reach 0 (perhaps something like num-=1)

Answer 3

My best guess would be that you may be entering too big of a number and the SL playground is just incapable of running for too long, returning that error. It's good to sometimes check with other IDEs as the code playground can limit you sometimes as to what you can do

Answer 4

Oh sorry I missed that! Running the code seems to work well for me, without returning any errors 🤔
Are you running it on the SL code playground?

Answer 5

Yes,thanks for help.

Answer 6

My pleasure

Answer 7

But i kept the exit condition num/=10,which will become zero in last.so,the while loop will exit.But even then it shows time limit and memory limit exceeded.

Answer 8

Yes,i am.

Answer 9

But thanks for your suggestions it executed successfully in eclipse.

Answer 10

Thanks for your opinion,it executed successfully.
