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 $0 \le F \le N$ 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 $1 \le X \le N$).

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 $F$?
