1989. Maximum Number of People That Can Be Caught in Tag π
Description
You are playing a game of tag with your friends. In tag, people are divided into two teams: people who are "it", and people who are not "it". The people who are "it" want to catch as many people as possible who are not "it".
You are given a 0-indexed integer array team
containing only zeros (denoting people who are not "it") and ones (denoting people who are "it"), and an integer dist
. A person who is "it" at index i
can catch any one person whose index is in the range [i - dist, i + dist]
(inclusive) and is not "it".
Return the maximum number of people that the people who are "it" can catch.
Example 1:
Input: team = [0,1,0,1,0], dist = 3 Output: 2 Explanation: The person who is "it" at index 1 can catch people in the range [i-dist, i+dist] = [1-3, 1+3] = [-2, 4]. They can catch the person who is not "it" at index 2. The person who is "it" at index 3 can catch people in the range [i-dist, i+dist] = [3-3, 3+3] = [0, 6]. They can catch the person who is not "it" at index 0. The person who is not "it" at index 4 will not be caught because the people at indices 1 and 3 are already catching one person.
Example 2:
Input: team = [1], dist = 1 Output: 0 Explanation: There are no people who are not "it" to catch.
Example 3:
Input: team = [0], dist = 1 Output: 0 Explanation: There are no people who are "it" to catch people.
Constraints:
1 <= team.length <= 105
0 <= team[i] <= 1
1 <= dist <= team.length
