题目

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
二进制数组中最多的连续'1'的个数

##解答
###解法1:(我)每次'0'时取max,但返回需要再取一次max(12ms)
```
public class Solution {
public int findMaxConsecutiveOnes(int[] nums) {
int count = 0;
int count1 = 0;
for (int i = 0; i
###解法2:每次'1'时取max,返回无需再取;遍历数组由for改为for each(9ms√)
```
public class Solution {
public int findMaxConsecutiveOnes(int[] nums) {
int count = 0;
int result = 0;
for (int num : nums){
if(num == 1){
count++;
result = Math.max(count,result);
}
else{
count = 0;
}
}
return result;
}
}
```
