Queens Chess Challenge – Small Basic

Make sure you check out LitDev’s January challenges.

Here’s more info about Amir CPS‘s Challenge: 8-Queens!

The 8-Queens problem in chess is to place 8 queens on a chess board such that none of the queens is threatening any of the others.  The problem is to input the 8 columns of the queens on the rows of a chess board, with 1 being the first column and 8 being the last, e.g. 1 2 3 4 5 6 7 8 means the queens are along the diagonal, which would not be a valid solution.

Write a program to test a user input guess.


  • Enter board configuration: 2 4 6 8 3 1 7 5 – This is a valid configuration (as above).
  • Enter board configuration: 1 8 2 5 3 7 4 6 – This is NOT a valid configuration.
Nonki took a crack at solving this challenge:


Black queens means valid and red queens means NOT valid.
