Computations

• Addition - add the numbers
• Multiplication - multiply the numbers
• Subtraction - subtract the numbers

Examples

• Example 1:

  Sample Input: 1 1 1 1 1 SEQUENTIAL

  Sample Output: ERROR: "At least 2 numbers must be different"

  Explanation: All five numbers are with the same value "1".

• Example 2:

  Sample Input: 3 4 1 5 6 SEQUENTIAL

  Sample Output: Add: 19 Multi: 360 Sub: -7 Time: 10s Type: SEQUENTIAL Numbers: [6, 5, 4, 3, 1]

  Explanation: in this case, Add operation executed first and took 2s. Then Mult operation executed and took 5s. Finally Sub operation took 3s, giving a total of 10s.

• Example 3:

  Sample Input: 5 4 5 5 5 PARALLEL

  Sample Output: Mult: 20 Sub: 1 Add: 9 Time: 5s Type: PARALLEL Numbers: [5, 4]

  Explanation: in this case, Add (5s), Mult (1s) and Sub (4s) operations started at the same time and the longest one defined the final execution time result of 5s.
