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.

找出最大連續 1 的次數在這個陣列

直覺是想計算到底出現幾次並且記錄下來，以及紀錄一個過去出現過的最大累積次數，如果這次的連續次數超過過去的最大次數，就把此次的最大數記為過去累積最大次數。

func findMaxConsecutiveOnes(nums []int) int {
    r := 0
    max := r
    for i := 0; i < len(nums); i++{
        if nums[i] == 1 {
            r++
            if r > max {
                max = r
            }
        } else {
            r = 0
        }
    }
    return max
}
