Hi We have a family game when we are stuck in traffic similar to https://en.wikipedia.org/wiki/Countdown_(game_show) (I know I am a nerd ) In the game we are looking at license plate of the car in front and trying to get 120 using the 4 arithmetic operators (+-*/) and the numbers in the license plate in the same order as they appear there. For example: If the license plate is 212614 2+1+2*6*1*4=120. Obviously there is no solution for all the plates, but I would like to write a small program to find the solution (if exist) to check myself. I can write a brute force algorithm that will go through all the options, but I wonder if there is a better algorithm. Can you suggest a better solution?
