Hey @anubhavb11
you will be given a number, you are allowed to “invert” some digits in this number. Inverting a digit means that you can replace the digit t with 9-t so some of the inversion pairs are

1, 8
2, 7
3, 6, and so on

You have to invert some of the digits in the given number such that the minimum possible number is made.

for eg for the given number 4545 you can make the numbers like these by inverting digits

4444,
5445,
4454,
5454,
5555,
It is clear that the minimum possible number is 4444

Hey @anubhavb11
You’ve to keep one thing in mind,
If the first digit of the number is 9, you can’t change it to 0,
Coz the number of digits in your number will be reduced,handle this thing in your code.
