Write a function that returns the sum of two numbers.

Example

For param1 = 1 and param2 = 2, the output should be
solution(param1, param2) = 3.

Input/Output

• [execution time limit] 4 seconds (js)

• [memory limit] 1 GB

• [input] integer param1

  Guaranteed constraints:
  -1000 ≤ param1 ≤ 1000.

• [input] integer param2

  Guaranteed constraints:
  -1000 ≤ param2 ≤ 1000.

• [output] integer

  The sum of the two inputs.
