+/**
+ * EggDropping
+ * You are given k identical eggs and you have access to a building with n
+ * floors labeled from 1 to n.
+ * 
+ * You know that there exists a floor f where 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 unbroken egg and drop it from any floor x (where 1
+ * <= x <= n).
+ * If the egg breaks, you can no longer use it. However, if the egg does not
+ * break, you may reuse it in future moves.
+ * 
+ * Return the minimum number of moves that you need to determine with certainty
+ * what the value of f is.
+ * 
+ * Example 1:
+ * 
+ * Input: k = 1, n = 2
+ * Output: 2
+ * Explanation:
+ * Drop the egg from floor 1. If it breaks, we know that f = 0.
+ * Otherwise, drop the egg from floor 2. If it breaks, we know that f = 1.
+ * If it does not break, then we know f = 2.
+ * Hence, we need at minimum 2 moves to determine with certainty what the value
+ * of f is.
