Fast & Functions Challenge (Java or Erlang)
Write code that implements the described functions to be executed as fast as possible:
- Build a function that given a list of Integers in the range [-65000,65000], the function
returns true if any subset of the list summed is equal to zero. False otherwise.
Example:
■ [0, 1, 2, -3] returns true. As 1+2+(-3)==0.
■ [1, 2, 3, -8] returns false. As no subset summed is equal 0.
■ [1, 4, 5, 2, -3] returns true.
- Build a function that given a list of Integers pairs in the range [-65000,65000], that represents {X, Y} Coordinates in a Plane. The function returns the two closest pairs.
○ Example:
■ [{0,0}, {1,20}, {5, 2}] returns [{0,0}, {5, 2}]
■ [{-10,10}, {1,5}, {4, 3}] returns [{1,5}, {4, 3}]
