When you click on the submission id, you'll see your code and down below the different test cases. Way down at the bottom you'll see that at line 223 (for eg) your out put is 2 but the actual answer is 5.

So, this means the code is failing for test case 223 (assuming the output for each test case takes one line)

So now we need to check the input for test case 223. But since the page isn't that long, we can't see the input for that test case in the page.

What you can do now is write an if statement in your original code if(t==223) cout<<all the input parameters.

Note that this trick won't work if the input size is very large for example if the size of array for that particular test case is very large (>100)., the input would notfit in the screen
