{ "data": { "question": { "questionId": "2206", "questionFrontendId": "2101", "categoryTitle": "Algorithms", "boundTopicId": 1149833, "title": "Detonate the Maximum Bombs", "titleSlug": "detonate-the-maximum-bombs", "content": "
You are given a list of bombs. The range of a bomb is defined as the area where its effect can be felt. This area is in the shape of a circle with the center as the location of the bomb.
\n\nThe bombs are represented by a 0-indexed 2D integer array bombs
where bombs[i] = [xi, yi, ri]
. xi
and yi
denote the X-coordinate and Y-coordinate of the location of the ith
bomb, whereas ri
denotes the radius of its range.
You may choose to detonate a single bomb. When a bomb is detonated, it will detonate all bombs that lie in its range. These bombs will further detonate the bombs that lie in their ranges.
\n\nGiven the list of bombs
, return the maximum number of bombs that can be detonated if you are allowed to detonate only one bomb.
\n
Example 1:
\n\n\nInput: bombs = [[2,1,3],[6,1,4]]\nOutput: 2\nExplanation:\nThe above figure shows the positions and ranges of the 2 bombs.\nIf we detonate the left bomb, the right bomb will not be affected.\nBut if we detonate the right bomb, both bombs will be detonated.\nSo the maximum bombs that can be detonated is max(1, 2) = 2.\n\n\n
Example 2:
\n\n\nInput: bombs = [[1,1,5],[10,10,5]]\nOutput: 1\nExplanation:\nDetonating either bomb will not detonate the other bomb, so the maximum number of bombs that can be detonated is 1.\n\n\n
Example 3:
\n\n\nInput: bombs = [[1,2,3],[2,3,1],[3,4,2],[4,5,3],[5,6,4]]\nOutput: 5\nExplanation:\nThe best bomb to detonate is bomb 0 because:\n- Bomb 0 detonates bombs 1 and 2. The red circle denotes the range of bomb 0.\n- Bomb 2 detonates bomb 3. The blue circle denotes the range of bomb 2.\n- Bomb 3 detonates bomb 4. The green circle denotes the range of bomb 3.\nThus all 5 bombs are detonated.\n\n\n

Constraints:
\n\n1 <= bombs.length <= 100
bombs[i].length == 3
1 <= xi, yi, ri <= 105
给你一个炸弹列表。一个炸弹的 爆炸范围 定义为以炸弹为圆心的一个圆。
\n\n炸弹用一个下标从 0 开始的二维整数数组 bombs
表示,其中 bombs[i] = [xi, yi, ri]
。xi
和 yi
表示第 i
个炸弹的 X 和 Y 坐标,ri
表示爆炸范围的 半径 。
你需要选择引爆 一个 炸弹。当这个炸弹被引爆时,所有 在它爆炸范围内的炸弹都会被引爆,这些炸弹会进一步将它们爆炸范围内的其他炸弹引爆。
\n\n给你数组 bombs
,请你返回在引爆 一个 炸弹的前提下,最多 能引爆的炸弹数目。
\n\n
示例 1:
\n\n\n\n输入:bombs = [[2,1,3],[6,1,4]]\n输出:2\n解释:\n上图展示了 2 个炸弹的位置和爆炸范围。\n如果我们引爆左边的炸弹,右边的炸弹不会被影响。\n但如果我们引爆右边的炸弹,两个炸弹都会爆炸。\n所以最多能引爆的炸弹数目是 max(1, 2) = 2 。\n\n\n
示例 2:
\n\n\n\n输入:bombs = [[1,1,5],[10,10,5]]\n输出:1\n解释:\n引爆任意一个炸弹都不会引爆另一个炸弹。所以最多能引爆的炸弹数目为 1 。\n\n\n
示例 3:
\n\n\n\n输入:bombs = [[1,2,3],[2,3,1],[3,4,2],[4,5,3],[5,6,4]]\n输出:5\n解释:\n最佳引爆炸弹为炸弹 0 ,因为:\n- 炸弹 0 引爆炸弹 1 和 2 。红色圆表示炸弹 0 的爆炸范围。\n- 炸弹 2 引爆炸弹 3 。蓝色圆表示炸弹 2 的爆炸范围。\n- 炸弹 3 引爆炸弹 4 。绿色圆表示炸弹 3 的爆炸范围。\n所以总共有 5 个炸弹被引爆。\n\n\n
