[Lucky Algorithm] Breaking the Records (13/77)

Breaking the Records (Hacker Rank)

Maria plays games of college basketball in a season. Because she wants to go pro, she tracks her points scored per game sequentially in an array defined as . After each game , she checks to see if score breaks her record for most or least points scored so far during that season.

Given Maria’s array of for a season of games, find and print the number of times she breaks her record for most and least points scored during the season.

Note: Assume her records for most and least points at the start of the season are the number of points scored during the first game of the season.
