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
Solution:
class Solution {
public int findMaxConsecutiveOnes(int[] nums) {
int n = nums.length;
int[] dp = new int[n];
dp[0] = nums[0];
int max = dp[0];
for (int i = 1; i < n; i ++) {
dp[i] = nums[i] == 1 ? dp[i - 1] + 1 : 0;
max = Math.max(max, dp[i]);
}
return max;
}
}
