Random Crypto Problem Solutions

Abstract

This page details the solutions to ten random cryto problems and my thoughts on the most salient aspect of the solutions.

Problem/Solution/MSAs

  1. numbers = {2,5,9,2,5} and goal = 6
    2. ((9/(5-2))+(5-2))
    3 was used twice in this solution, both being made in the same way by (5-2)
  2. numbers = {0,2,2,9,4} and goal = 0
    3. (0*(((2+2)+9)+4))
    This solution was trivial because 0 can always be used to make 0 via multiplication
  3. numbers = {9,1,5,3,4} and goal = 8
    4. ((5-9)+(4*3)*1)
    This solution utilizes a negative number
  4. numbers = {9,2,4,0,6} and goal = 8
    5. ((2*4)+(((9*6)*4)*0))
    Getting 8 could be done with just one operation (2*4) and having a zero made it possible to zero out the rest of the inputs with multiplication
  5. numbers = {3,5,2,7,2} and goal = 4
    6. (((7-5)+2)*(3-2))
    This problem is basically 2+2
  6. numbers = {4,6,3,6,4} and goal = 5
    7. (3+((4/4)+(6/6)))
    One is made twice here
  7. numbers = {5,6,3,6,0} and goal = 4
    8. ((6-3)+((6-5)+0))
    Subtraction is utilized twice here
  8. numbers = {1,4,5,7,0} and goal = 4
    9. ((1*4)+(5*(7*0)))
    This solution follows the order of the numbers in problem
  9. numbers = {4,6,7,8,4} and goal = 3
    10. (6/((4/4)+(8-7)))
    This solution uses 2 divisions and a subtraction operation
  10. numbers = {9,8,9,9,2} and goal = 2
    11. ((9-((8*9)/9))*2)
    This solution again follows the order of the numbers in the problem
