greedy unacademy tryin to monetize everything.
Codechef is no longer owned by Unacademy.

Thanks for pointing this out. We are looking into it, and will update.
It was indeed a Notorious Coincidence. We apologize for the oversight. The proposer has been banned from the platform.
What does exactly mean in problem C?
You have to do 2 moves,no more no less even if the strings are equal initially.
Casework: At the position where t[i]!=s[i], we have to definitely apply a single operational and at the position where characters are equal, we can apply no operational or two operations. Consider 1 when t[i]=s[i] otherwise 0. Then count the number of continuous 0 and 1. Let them be c1 and c2 then:
x=total number of 1 and y=total number of 0
Can anyone tell my mistake in this code for " Chef Segment " problem
