Tiny Interview: Python Nested Loops Optimization

Coding Challenges

For this tiny interview, you’re to implement a function which finds four numbers within the provided list which have a sum equal to the target.

An example is provided, but is too slow on larger testcases because it has too many nested loops.

  • There will always be at least one valid quadruplet.
  • The same number can be used any number of times.
  • Numbers can be returned in any order.
