Today I have done leetcode's August LeetCoding Challenge with cpp.

August LeetCoding Challenge 5

Description

Fruits Into Baskets II

You are given two arrays of integers, fruits and baskets, each of length n, where fruits[i] represents the quantity of the ith type of fruit, and baskets[j] represents the capacity of the jth basket.

From left to right, place the fruits according to these rules:

  • Each fruit type must be placed in the leftmost available basket with a capacity greater than or equal to the quantity of that fruit type.
  • Each basket can hold only one type of fruit.
  • If a fruit type cannot be placed in any basket, it remains unplaced.

Return the number of fruit types that remain unplaced after all possible allocations are made.

 

Example 1:

Input: fruits = [4,2,5], baskets = [3,5,4]

Output: 1

Explanation:

  • fruits[0] = 4 is placed in baskets[1] = 5.
  • fruits[1] = 2 is placed in baskets[0] = 3.
  • fruits[2] = 5 cannot be placed in baskets[2] = 4.

Since one fruit type remains unplaced, we return 1.

Example 2:

Input: fruits = [3,6,1], baskets = [6,4,7]

Output: 0

Explanation:

  • fruits[0] = 3 is placed in baskets[0] = 6.
  • fruits[1] = 6 cannot be placed in baskets[1] = 4 (insufficient capacity) but can be placed in the next available basket, baskets[2] = 7.
  • fruits[2] = 1 is placed in baskets[1] = 4.

Since all fruits are successfully placed, we return 0.

 

Constraints:

  • n == fruits.length == baskets.length
  • 1 <= n <= 100
  • 1 <= fruits[i], baskets[i] <= 1000

Solution

class Solution {
public:
  int numOfUnplacedFruits(vector<int>& fruits, vector<int>& baskets) {
    int answer = 0;
    for(auto f : fruits) {
      for(auto &b : baskets) {
        if(b < f)  continue;
        b = 0;
        f = 0;
        break;
      }
      answer += !!f;
    }
    return answer;
  }
};
