You are given K eggs, and you have access to a building with N floors from 1 to N.
Each egg is identical in function, and if an egg breaks, you cannot drop it again.
You know that there exists a floor F with 0 <= F <= N such that any egg dropped at a floor higher than F will break, and any egg dropped at or below floor F will not break.
Each move, you may take an egg (if you have an unbroken one) and drop it from any floor X (with 1 <= X <= N).
Your goal is to know with certainty what the value of F is.
What is the minimum number of moves that you need to know with certainty what F is, regardless of the initial value of F?
Example 1:
Input: K = 1, N = 2 Output: 2 Explanation: Drop the egg from floor 1. If it breaks, we know with certainty that F = 0. Otherwise, drop the egg from floor 2. If it breaks, we know with certainty that F = 1. If it didn't break, then we know with certainty F = 2. Hence, we needed 2 moves in the worst case to know what F is with certainty.
Example 2:
Input: K = 2, N = 6 Output: 3
Example 3:
Input: K = 3, N = 14 Output: 4
Note:
1 <= K <= 1001 <= N <= 10000
