There is a car with capacity empty seats. The vehicle only drives east (i.e., it cannot turn around and drive west).

\n\n

You are given the integer capacity and an array trips where trips[i] = [numPassengersi, fromi, toi] indicates that the ith trip has numPassengersi passengers and the locations to pick them up and drop them off are fromi and toi respectively. The locations are given as the number of kilometers due east from the car's initial location.

\n\n

Return true if it is possible to pick up and drop off all passengers for all the given trips, or false otherwise.

\n\n

 

\n

Example 1:

\n\n
\nInput: trips = [[2,1,5],[3,3,7]], capacity = 4\nOutput: false\n
\n\n

Example 2:

\n\n
\nInput: trips = [[2,1,5],[3,3,7]], capacity = 5\nOutput: true\n

车上最初有 capacity 个空座位。车 只能 向一个方向行驶（也就是说，不允许掉头或改变方向）

\n\n

给定整数 capacity 和一个数组 trips ,  trips[i] = [numPassengersi, fromi, toi] 表示第 i 次旅行有 numPassengersi 乘客，接他们和放他们的位置分别是 fromi 和 toi 。这些位置是从汽车的初始位置向东的公里数。

\n\n

当且仅当你可以在所有给定的行程中接送所有乘客时，返回 true，否则请返回 false。

\n\n

 

\n\n

示例 1：

\n\n
\n输入：trips = [[2,1,5],[3,3,7]], capacity = 4\n输出：false\n

示例 2：

\n\n
\n输入：trips = [[2,1,5],[3,3,7]], capacity = 5\n输出：true\n
