candies 양의 정수 배열은 각 index 별로 아이들이 가지고 있는 캔디 수를 의미합니다.

아이에게 extraCandies를 주면 아이들 중에 가장 많은 캔디를 가질 수 있는지 없는지를 판별하여

boolean 배열을 반환합니다.

 

javascript

/**
 * @param {number[]} candies
 * @param {number} extraCandies
 * @return {boolean[]}
 */
const kidsWithCandies = (candies, extraCandies) => {
  const greatestNum = Math.max(...candies)
  const result = candies.map(kid => kid + extraCandies >= greatestNum)
  return result
}

typescript

const kidsWithCandiesTS = (candies: number[], extraCandies: number): boolean[] => {
  const greatestNum: number = Math.max(...candies)
  const result: boolean[] = candies.map(kid => kid + extraCandies >= greatestNum)
  return result
}

golang

func kidsWithCandies(candies []int, extraCandies int) []bool {
	var result = make([]bool, len(candies))
	var greatestNum int = candies[0]
	for i := 0; i < len(candies); i++ {
		if greatestNum < candies[i] {
			greatestNum = candies[i]
		}
	}
	for index, kid := range candies {
		if kid+extraCandies >= greatestNum {
			result[index] = true
		}
	}
	return result
}
