Breaking the Records [Hacker Rank]

Question

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.

Function Description

Complete the breakingRecords function in the editor below.

breakingRecords has the following parameter(s):

• int scores[n]: points scored per game

Returns

• int[2]: An array with the numbers of times she broke her records. Index is for breaking most points records, and index is for breaking least points records.

Input Format

The first line contains an integer n, the number of games.
The second line contains n space-separated integers describing the respective values of score(0), score(1), ... score(n-1).

Constraints

• 1 < n <= 1000
• 0 <= scores[i] <= 10^8

농구 점수가 정수 리스트로 주어질 때, 최고 기록과 최저 기록이 갱신되는 횟수를 return하는 문제다.

1. 먼저 나는 result에 갱신 횟수를 담기위해 [0,0]배열로 선언해주었다.
2. scores를 돌면서 최저기록 혹은 최고기록이 갱신되는지 확인하며 갱신되었다면 result의 해당 인덱스에 +1 해준다.
3. 갱신되었을 때, 기록도 갱신된 기록으로 바꿔준다.
4. result를 return한다.
