minimum-number-of-arrows-to-burst-balloons 题目内容 在二维空间中有许多球形的气球。对于每个气球,提供的输入是水平方向上,气球直径的开始和结束坐标。由于它是水平的,所以纵坐标并不重要,因此只要知道开始和结束的横坐标就足够了。开始坐标总是小于结束坐标。 一支弓箭可以沿着 x 轴从不同点完全垂直地射出。在坐...
An arrow can be shot up exactly vertically from different points along the x-axis. A balloon with xstart and xend bursts by an arrow shot at x if xstart ≤ x ≤ xend. There is no limit to the number of arrows that can be shot. An arrow once shot keeps travelling up infinitely. The...
452. Minimum Number of Arrows to Burst Balloons There are a number of spherical balloons spread in two-dimensional space. For each balloon, provided input is the start and end coordinates of the horizontal diameter. Since it’s horizontal, y-coordinates don’t matter and hence the x-coordinate...
Given the arraypoints, returntheminimumnumber of arrows that must be shot to burst all balloons. Example 1: Input: points = [[10,16],[2,8],[1,6],[7,12]] Output: 2 Explanation: The balloons can be burst by 2 arrows: - Shoot an arrow at x = 6, bursting the balloons [2,8]...

题目描述:气球在一个水平数轴上摆放,可以重叠,飞镖垂直投向坐标轴,使得路径上的气球都会刺破。求解最小的投飞镖次数使所有气球都被刺破。 也是计算不重叠的区间个数,不过和 Non-overlapping Intervals 的区别在于,[1, 2] 和 [2, 3] 在本题中算是重叠区间。
