Row array gameScores contains all player scores. Construct a row array highScores than contains all player scores greater than m
Sever21 [200]

Answer:

The solution is written using Python as it has a simple syntax.

  1. def getHighScores(gameScores, minScore):
  2.    meetsThreshold = []
  3.    for score in gameScores:
  4.        if(score > minScore):
  5.            meetsThreshold.append(score)
  6.    return meetsThreshold
  7. gameScores = [2, 5, 7, 6, 1, 9, 1]
  8. minScore = 5
  9. highScores = getHighScores(gameScores, minScore)
  10. print(highScores)

Explanation:

Line 1-8

  • Create a function and name it as <em>getHighScores</em> which accepts two values, <em>gameScores</em> and <em>minScore</em>. (Line 1)
  • Create an empty list/array and assign it to variable <em>meetsThreshold</em>. (Line 2)
  • Create a for loop to iterate through each of the score in the <em>gameScores</em> (Line 4)
  • Set a condition if the current score is bigger than the <em>minScore</em>, add the score into the <em>meetsThreshold</em> list (Line 5-6)
  • Return <em>meetsThreshold</em> list as the output

Line 11-12

  • create a random list of <em>gameScores</em> (Line 11)
  • Set the minimum score to 5 (Line 12)

Line 13-14

  • Call the function <em>getHighScores()</em> and pass the<em> gameScores</em> and <em>minScore </em>as the arguments. The codes within the function <em>getHighScores()</em>  will run and return the <em>meetsThreshold </em>list and assign it to <em>highScores.</em> (Line 13)
  • Display <em>highScores</em> using built-in function print().
