Max Consecutive Ones

Description

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(javascript)

/**
 * @param {number[]} nums
 * @return {number}
 */
const findMaxConsecutiveOnes = function (nums) {
  let max = 0
  let current = 0
  for (let index = 0; index < nums.length; index++) {
    if (nums[index] === 1) {
      current += 1
    } else {
      current = 0
    }
    max = Math.max(current, max)
  }
  return max
}
