for input

1

10 2

9 9

6 6

the correct Answer is 87

LCM not required,once sorted

Thanks a lot sir for replying but from the problem statement

https://www.codechef.com/AUG21C/problems/ARRFILL

for operation 1:

except 9 all 9 holes will be filled by 9

By Operation 2:the hole 9 also filled by 6

87 will be the value

LCM not required, if sorted by xi

please provide failure case

I am using Product of y’s not LCM’s of y’s

Each testcase containing x_{i+k} being a multiple of x_i for arbitrary k should mess with your implementation.

Try for example

1

10 2

10 3

7 6

Your solution: 91

Actual solution: 84

Thank you sir
