Please help me in finding the error in my code?

#1


my code

#2

there is one mistake

don’t sort the array otherwise it will give wrong ans
because in question it is mention that

Every painter can paint only contiguous segments of boards.

so if you sort the array contiguous will not remain contiguous

so no need to sort the array

now start=*max_element(arr,arr+n)
you can see the changes in modified code

Modified Code

if you have more doubts regarding this feel free to ask
i hope this helps
if yes hit a like :heart:: and don’t forgot to mark doubt as resolved :grinning:
