Restricted Sum

Restricted Sum


Our new calculator is censored and as such it does not accept certain words. You should try to trick by writing a program to calculate the sum of numbers.

Given a list of numbers, you should find the sum of these numbers. Your solution should not contain any of the banned words, even as a part of another word.

The list of banned words are as follows:

  • sum
  • import
  • for
  • while
  • reduce

Input: A list of numbers.

Output: The sum of numbers.
