Max Consecutive Ones

desc posit 統計次數 計算 input public arr col amp

Given a binary array, find the maximum number of consecutive 1s in this array.

Example 1:

Input: [1,1,0,1,1,1]
Output: 3
Explanation: The first two digits or the last three digits are consecutive 1s.
    The maximum number of consecutive 1s is 3.

Note:

  • The input array will only contain 0 and 1.
  • The length of input array is a positive integer and will not exceed 10,000

分析:計算1連續出現的最大次數。

思路:遍歷統計次數,記錄下連續出現的次數即可。

JAVA CODE

class Solution {
    public int findMaxConsecutiveOnes(int[] nums) {
        int times = 0, maxTimes = 0;
        for(int i = 0; i < nums.length; i++){
            if(nums[i] == 0){
                maxTimes = maxTimes > times ? maxTimes : times;
                times 
= 0; }else{ times++; } } return maxTimes = maxTimes > times ? maxTimes : times; } }
