2644. Find the Maximum Divisibility Score

Easy

You are given two 0-indexed integer arrays nums and divisors.

The divisibility score of divisors[i] is the number of indices j such that nums[j] is divisible by divisors[i].

Return the integer divisors[i] with the maximum divisibility score. If there is more than one integer with the maximum score, return the minimum of them.

Example 1:

Input: nums = [4,7,9,3,9], divisors = [5,2,3]

Output: 3

Explanation: The divisibility score for every element in divisors is:

The divisibility score of divisors[0] is 0 since no number in nums is divisible by 5.

The divisibility score of divisors[1] is 1 since nums[0] is divisible by 2.

The divisibility score of divisors[2] is 3 since nums[2], nums[3], and nums[4] are divisible by 3.

Since divisors[2] has the maximum divisibility score, we return it.

Example 2:

Input: nums = [20,14,21,10], divisors = [5,7,5]

Output: 5

Explanation: The divisibility score for every element in divisors is:

The divisibility score of divisors[0] is 2 since nums[0] and nums[3] are divisible by 5.

The divisibility score of divisors[1] is 2 since nums[1] and nums[2] are divisible by 7.

The divisibility score of divisors[2] is 2 since nums[0] and nums[3] are divisible by 5.

Since divisors[0], divisors[1], and divisors[2] all have the maximum divisibility score, we return the minimum of them (i.e., divisors[2]).

Example 3:

Input: nums = [12], divisors = [10,16]

Output: 10

Explanation: The divisibility score for every element in divisors is:

The divisibility score of divisors[0] is 0 since no number in nums is divisible by 10.

The divisibility score of divisors[1] is 0 since no number in nums is divisible by 16.

Since divisors[0] and divisors[1] both have the maximum divisibility score, we return the minimum of them (i.e., divisors[0]).

Solution

class Solution {
    fun maxDivScore(nums: IntArray, divisors: IntArray): Int {
        var maxDivisor = divisors.first()
        var maxDividedNums = 0
        for (divisor in divisors) {
            var dividedNums = 0
            for (num in nums) {
                if (num % divisor == 0)
                    dividedNums++
            }
            if (dividedNums > maxDividedNums) {
                maxDividedNums = dividedNums
                maxDivisor = divisor
            }
            if (dividedNums == maxDividedNums && divisor < maxDivisor)
                maxDivisor = divisor
        }
        return maxDivisor
    }
}
