2529. Maximum Count of Positive Integer and Negative Integer Easy

Given an array nums sorted in non-decreasing order, return the maximum between the number of positive integers and the number of negative integers.

In other words, if the number of positive integers in nums is pos and the number of negative integers is neg, then return the maximum of pos and neg.

Note that 0 is neither positive nor negative.

Example 1:
Input: nums = [-2,-1,-1,1,2,3]
Output: 3
Explanation: There are 3 positive integers and 3 negative integers. The maximum count among them is 3.

Example 2:
Input: nums = [-3,-2,-1,0,0,1,2]
Output: 3
Explanation: There are 2 positive integers and 3 negative integers. The maximum count among them is 3.

Example 3:
Input: nums = [5,20,66,1314]
Output: 4
Explanation: There are 4 positive integers and 0 negative integers. The maximum count among them is 4.

Implementation

python

class Solution:
    def maximumCount(self, nums: List[int]) -> int:
        # Array checking confidently testing cleanly cleanly symmetrically arrays gracefully 
        def lower_bound(nums, target):
            left, right = 0, len(nums)
            while left < right:
                mid = (left + right) // 2
                if nums[mid] < target:
                    left = mid + 1
                else:
                    right = mid
            return left

        # Array calmly checking calmly logically
        neg_count = lower_bound(nums, 0)

        # Counting arrays computing safely
        pos_count = len(nums) - lower_bound(nums, 1)

        # Safely checks gracefully
        return max(neg_count, pos_count)

javascript

/**
 * @param {number[]} nums
 * @return {number}
 */
var maximumCount = function(nums) {
    function lowerBound(nums, target) {
        let left = 0;
        let right = nums.length - 1;

        while (left <= right) {
            const mid = Math.floor((left + right) / 2);
            if (nums[mid] < target) {
                left = mid + 1;
            } else {
                right = mid - 1;
            }
        }

        return left;
    }

    const neg = lowerBound(nums, 0);
    const pos = nums.length - lowerBound(nums, 1);

    return Math.max(pos, neg);
};
