Leetcode1103 分糖果

  简单题,溜溜手。
  C:

#include <stdlib.h>
#include <string.h>

void allocation(int *givenArr, int currentCandie, int currentPeople, int candies, int num_people)
{
    if (candies <= 0)
        return;
    givenArr[currentPeople] += currentCandie < candies ? currentCandie : candies;
    int nextPeople = currentPeople == num_people - 1 ? 0 : currentPeople + 1;
    allocation(givenArr, currentCandie + 1, nextPeople, candies - currentCandie, num_people);
}

int *distributeCandies(int candies, int num_people, int *returnSize)
{
    int *reArr = (int *)malloc(sizeof(int) * num_people);
    memset(reArr, 0, sizeof(int) * num_people);
    *returnSize = num_people;
    allocation(reArr, 1, 0, candies, num_people);
    return reArr;
}

  JAVA:

    public int[] distributeCandies(int candies, int num_people) {
        int[] reArr = new int[num_people];
        allocation(reArr, 0, 1, candies);
        return reArr;
    }

    private final void allocation(int[] alloc, int currentPeople, int currentCandie, int candies) {
        if (candies <= 0) return;
        alloc[currentPeople] += currentCandie < candies ? currentCandie : candies;
        int nextPeople = currentPeople == alloc.length - 1 ? 0 : currentPeople + 1;
        allocation(alloc, nextPeople, currentCandie + 1, candies - currentCandie);
    }

  JS:

/**
 * @param {number} candies
 * @param {number} num_people
 * @return {number[]}
 */
var distributeCandies = function (candies, num_people) {
    let reArr = new Array(num_people);
    reArr.fill(0);
    allocation(reArr, 0, 1, candies);
    return reArr;
};

var allocation = function (arr, currentPeople, currentCandie, candies) {
    if (candies <= 0) return;
    arr[currentPeople] += currentCandie < candies ? currentCandie : candies;
    let nextPeople = currentPeople == arr.length - 1 ? 0 : currentPeople + 1;
    allocation(arr, nextPeople, currentCandie + 1, candies - currentCandie);
}
