  • # Challenge
  • Make a program that takes input of 3 non-negative integers: a result and 2 other values that once calculated results to the 3rd value.
  • - The program must figure out how to get the 2 first numbers to equivalence itself with the 3rd. It could be either addition, subtraction, multiplication, integer division, modulo and exponentiation.
  • - You can't change the places of the 2 variables when building the equation, meaning you can't get some value by intertwining in the methods excluding addition and multiplication.
  • - The returning value is the operator that makes the equation true (it's best to use some distinguishable character to separate it from the other methods).
  • - Use whatever characters you want to use to determine the method that makes the equation truthy.
  • - If multiple operators make the equation truthy, then output them in any order.
  • - What makes it true? If an equation exists within the 2 numbers that results to the value of the 3rd.
  • - What to return when it's false? Something but not nothing (whitespaces and newlines aren't allowed as such output).
  • - This is <a class="badge is-tag">code-golf</a> so the shortest program wins!

Operation "Find The Operator"
> This challenge is currently under beta. Use the [Sandbox](https://codegolf.codidact.com/posts/284407/) to fix any issues of the challenge, not on this post.

# Challenge

Make a program that takes input of 3 non-negative integers: a result and 2 other values that once calculated results to the 3rd value.

- The program must figure out how to get the 2 first numbers to equivalence itself with the 3rd. It could be either addition, subtraction, multiplication, integer division, modulo and exponentiation.
- You can't change the places of the 2 variables when building the equation, meaning you can't get some value by intertwining in the methods excluding addition and multiplication.
- The returning value is the operator that makes the equation true (it's best to use some distinguishable character to separate it from the other methods).
- If multiple operators make the equation truthy, then output them in any order.
- What makes it true? If an equation exists within the 2 numbers that results to the value of the 3rd.
- What to return when it's false? Something but not nothing (whitespaces and newlines aren't allowed as such output).
- This is <a class="badge is-tag">code-golf</a> so the shortest program wins!
