3332 - Maximum Points Tourist Can Earn.

Medium

You are given two integers, n and k, along with two 2D integer arrays, stayScore and travelScore.

A tourist is visiting a country with n cities, where each city is directly connected to every other city. The tourist's journey consists of exactly k 0-indexed days, and they can choose any city as their starting point.

Each day, the tourist has two choices:

• Stay in the current city: If the tourist stays in their current city curr during day i, they will earn stayScore[i][curr] points.

• Move to another city: If the tourist moves from their current city curr to city dest, they will earn travelScore[curr][dest] points.

Return the maximum possible points the tourist can earn.

Example 1:

Input: n = 2, k = 1, stayScore = [2,3], travelScore = [0,2,1,0]

Output: 3

Explanation:

The tourist earns the maximum number of points by starting in city 1 and staying in that city.

Example 2:

Input: n = 3, k = 2, stayScore = [3,4,2,2,1,2], travelScore = [0,2,1,2,0,4,3,2,0]

Output: 8

Explanation:

The tourist earns the maximum number of points by starting in city 1, staying in that city on day 0, and traveling to city 2 on day 1.

Constraints:

• 1 <= n <= 200

• 1 <= k <= 200

• n == travelScore.length == travelScore[i].length == stayScore[i].length

• k == stayScore.length

• 1 <= stayScore[i][j] <= 100

• 0 <= travelScore[i][j] <= 100

• travelScore[i][i] == 0
