Chewbacca and numbers

#1


only 3 test case running

#2

Hey @bhattanurag426 see for this test case: 332711047202
Your output is: 2142413342
But Expected output is: 332211042202
I can see the implementation you have followed is not ideal. If you want any idea for the implementation, then do let me know

#3

yes sir i want the idea for implementation

#4

What the questtion is asking is basically that what is the possible smallest number we can get by interchanging digits (changing t to 9-t) .
Now if we already have the smallest number that can be : we will change 0 digits
Otherwise we will change some digits to make it the smallest number

For ex : 4545 has two digits which when interchanged will give a smaller number ( 5 when interchanged will give 4 ) so all the 5 in the number arre changed and the output becomes 4444.

Hint : Change all the numbers with value >4 . But keep in mind that you cannot make the first number 0.

I am attaching my code here so that you can refer that also
