+/**
+ Given a binary array nums, return the maximum number of consecutive 1's in the array.
+
+  
+
+ Example 1:
+ Input: nums = [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.
+ 
+ Example 2:
+ Input: nums = [1,0,1,1,0,1]
+ Output: 2
+  
+
+ Constraints:
+ - 1 <= nums.length <= 105
+ - nums[i] is either 0 or 1.
