public class Solution extends Object
1936 - Add Minimum Number of Rungs\. Medium You are given a **strictly increasing** integer array `rungs` that represents the **height** of rungs on a ladder. You are currently on the **floor** at height `0`, and you want to reach the last rung. You are also given an integer `dist`. You can only climb to the next highest rung if the distance between where you are currently at (the floor or on a rung) and the next rung is **at most** `dist`. You are able to insert rungs at any positive **integer** height if a rung is not already there. Return _the **minimum** number of rungs that must be added to the ladder in order for you to climb to the last rung._ **Example 1:** **Input:** rungs = [1,3,5,10], dist = 2 **Output:** 2 **Explanation:** You currently cannot reach the last rung. Add rungs at heights 7 and 8 to climb this ladder. The ladder will now have rungs at [1,3,5,7,8,10]. **Example 2:** **Input:** rungs = [3,6,8,10], dist = 3 **Output:** 0 **Explanation:** This ladder can be climbed without adding additional rungs. **Example 3:** **Input:** rungs = [3,4,6,7], dist = 2 **Output:** 1 **Explanation:** You currently cannot reach the first rung from the ground. Add a rung at height 1 to climb this ladder. The ladder will now have rungs at [1,3,4,6,7]. **Constraints:** * 1 <= rungs.length <= 105 * 1 <= rungs[i] <= 109 * 1 <= dist <= 109 * `rungs` is **strictly increasing**.
