My code is showing case errors. Please help me in rectifying my code

#1

Here is my code.

#2

hi @sinchan1509_1a917d7b6cc3cbb9
Refer this code -->

#3

Why is my code not working??

#4

When u write int reverse, or int inverse, write long long int over there… it might work…

#5

It is still showing two cases error one is 0 at last gets eliminated and other I don’t know how to eliminate them by modifying my code??

hi @sinchan1509_1a917d7b6cc3cbb9
consider the input as 1000…
expected o/p --> 1000
your o/p --> 1

hence u will have to change ur approach as this issue is being caused due to reversing the no… refer the code I sent above… explanation for the above code -->
The logic behind this Problem was pretty simple as we can invert any digit ( 9 - digit) but we need to invert only such digits that will eventually end up giving the smallest number possible.

So, we should invert only digits greater then or equal to 5 as after inverting them, the result gives us smallest number.

For e.g.,

9 - 5 = 4 viz, smaller than the original number that was 5.

9 - 8 = 1 viz, smaller than the original number that was 8.

but 9 - 1 = 8 viz, greater than the original number that was 1.

Important point to consider is, After inverting any digits their should not be trailing zeros that means, if their is 9 at the starting of the number then it must remain the same

Also input can be quite big so, u need to capture the number in long long int in c++

ok i got it i am working on the code you sent. I will let you know once I am completely done with the q

#8

sure @sinchan1509_1a917d7b6cc3cbb9

#9

if(rem==9 && (n/10)==0){ // do nothing }

#10

Why is this code written what is the purpose is it for 0 in number??

#11

Yes @sinchan1509_1a917d7b6cc3cbb9

#12

ok thank you so much i didn’t copied your code as it is just made changes in my code after taking few things from yours
