OBTTRNGL : need help

can someone help me in my solution https://www.codechef.com/viewsolution/15055255

How is your code working if i give you A>B ?

Like, for k=10, A=10 and B=2?

You are printing -9 for this input.

Input
1
10 10 2
Your Output
-9
Correct Output
1 (Candle 1 is eligible)

I think I considered 1 ≤ A, B ≤ k as B is always greater than A.

Thats not guaranteed in input. A,B != A<=B :stuck_out_tongue:
