title: List Index out of Bounds (Arcade game)
body: <p>I have recently attended an interview and I was asked below question :</p>
  <p>Adam is so good at playing arcade games that he will win at every game he plays. One fine day as he was walking on the street, he discovers an arcade store that pays real cash for every game that the player wins - however, the store will only pay out once per game. The store has some games for which they will pay winners, and each game has its own completion time and payout rate. Thrilled at the prospect of earning money for his talent, Adam walked into the store only to realize that the store closes in 2 hours (exactly 120 minutes). Knowing that he cannot play all the games in that time, he decides to pick the games that maximize his earnings</p>
  <p>Sample game board at the arcade
  GAME    COMPLETION_TIME
  (in minutes)    PAYOUT_RATE</p>
  <pre><code>Pac-man 90  400
  Mortal Kombat   10  30
  Super Tetris    25  100
  Pump it Up  10  40
  Street Fighter II   90  450
  Speed Racer 10  40
  </code></pre>
  <p>An acceptable solution is the one where it still picks the best earnings even when the list of games or completion times or payout rates change.</p>
  <p>Question:
  Write code in Java/Scala/Python to help Adam pick the sequence(s) of games that earn him the most money.</p>
  <p>Then, assume you have a variable list of games and their payout rates. What is the best way to pick the games that earn you the most?</p>
  <p>Input Explanation:
  The first line of input is always an integer denoting many lines to read after the first line. In our sample test case, we have 6 in the first line and 6 lines after the first line, each having a game, completion_time and payout_rate.
  In each data line, the game, completion_time and payout_rate are separated by a ','(comma).
  The games board may change but the store still closes in 120 minutes.</p>
  <p>Input:
  6</p>
  <pre><code>Pac-man,80,400
  Mortal Kombat,10,30
  Super Tetris,25,100
  Pump it Up,10,40
  Street Fighter II,90,450
  Speed Racer,10,40
  </code></pre>
  <p>Output Explanation :
  Print the game names that earn him the most into the standard output in alphabetical order</p>
  <p>Output</p>
  <pre><code>Mortal Kombat
  Pump it Up
  Speed Racer
  Street Fighter II
  </code></pre>
  <p>Tried So far:</p>
  <pre><code>import sys
  import itertools
  
  line = sys.stdin.readline()
  def biggest_payout(line):
     
      a = line.split(sep=' ')

      for i in range(1, len(a)):
          b.append(a[i].split(sep=','))
      c = []
      for i in range(len(b)):
          c.append(int(b[i][1]))
      min_sums = []
      for L in range(0, len(c)+1):
          for subset in itertools.permutations(c, L):
              min_sums.append(sum(subset))
      e = []
      for i in range(len(b)):
          e.append(int(b[i][2]))
      money_sums = []
      for L in range(0, len(e)+1):
          for subset in itertools.permutations(e, L):

      while True:
          if min_sums[money_sums.index(max(money_sums))] &gt; 120:
              money_sums[money_sums.index(max(money_sums))] = 0
          else:
              index = money_sums.index(max(money_sums))
              break
      return movie_combos[index]
  
  for line in sys.stdin:       
         print(biggest_payout(line))
  </code></pre>
  <p>Error :</p>
  <pre><code>  File &quot;/temp/file.py&quot;, line 13, in biggest_payout
      c.append(int(b[i][1]))
  IndexError: list index out of range
  </code></pre>
  <p>I am getting array index outbounds, can some please guide me how to solve this?</p>
