#Code Challenge #13: July 5, 2017
Every week, we feature the type of brain-teasing question that might be asked in a full-stack developer’s job interview at places such as Google and Facebook.
This week’s challenge was reported to have been asked in interviews at Amazon:
You’ve spent decades setting high scores on Donkey Kong but now, a challenger approaches. Write a function,
scoreSettler, that will definitively show who is the King of Kong.
scoreSettlerwill take a list of unsorted scores plus the highest possible score and return a sorted list of all of the scores, in descending order from high score to low score.
list of integersrepresenting scores and a single
integerfor the highest possible score
Output: A sorted
list of integersin descending order
scoreSettler([ 1, 2, 3, 999999], 1000000) => [999999, 3, 2, 1]
- In your submission, please use as a test of your function the maximum value of
1218000, with a list of scores
[874300, 879200, 1172100, 1141800, 933900, 1177200, 1190200, 1110100, 1158400, 985600, 1047200, 1049100, 1138600, 1170500, 1064500, 1190000, 1050200, 1090400, 1062800, 1061700, 1218000, 1068000, 1127700, 1144800, 1195100]
- You’re expected to create and implement your own sorting algorithms, not to simply use an in-built sort function.
#####Find out more about basic challenges.
You wouldn’t be much of a King of Kong if your settling of the scores didn’t itself set records. Write
scoreSettleras efficiently as possible.
If you can’t make your program any more efficient explain why.
If you need an additional challenge, try to solve this problem in a more unconventional or artful way, or perhaps try a different language!
Reply to this thread with a link to your code on repl.it and paste your properly formatted code to participate! Don’t just submit your code, remember to
explain your solution, too! If you want to be considered as the winner, your function
must have the
correct name and provide
output in the format specified above, you also need to abide by our other simple rules.
As always solutions using imports to do all the heavy lifting such as
itertools will not be considered for the winner.
