[Implementation] Breaking the Records

문제 설명:

  Maria plays college basketball and wants to go pro. Each season she maintains a record of her play. She tabulates the number of times she breaks her season record for most points and least points in a game. Points scored in the first game establish her record for the season, and she begins counting from there.

 

Example

scores = [12, 24, 10, 24]

Scores are in the same order as the games played. She tabulates her results as follows:

                                     Count
    Game  Score  Minimum  Maximum   Min Max
     0      12     12       12       0   0
     1      24     12       24       0   1
     2      10     10       24       1   1
     3      24     10       24       1   1

Given the scores for a season, determine the number of times Maria breaks her records for most and least points scored during the season.

func breakingRecords(scores: [Int]) -> [Int] {
	// 최고 점수를 저장할 변수, 몇번 최고 점수를 기록했는지 담을 변수
    var bestScore = scores[0]
    var bestRecordCount = 0
	// 최저 점수를 저장할 변수, 몇번 최저 점수를 기록했는지 담을 변수  
    var leastScore = scores[0]
    var leastRecordCount = 0
    
    for score in scores {
    	// 기존의 최고점수가 새로운 점수보다 낮으면, 새로운 점수를 최고점수에 넣고 최고기록 + 1
        if bestScore < score {
            bestScore = score
            bestRecordCount += 1
        }
        // 기존의 최저점수가 새로운 점수보다 높으면, 새로운 점수를 최저점수에 넣고 최저기록 + 1
        if leastScore > score {
            leastScore = score
            leastRecordCount += 1
        }
    }
    return [bestRecordCount, leastRecordCount]
}
