Queens and Knights
You are given a 8x8 chess board with out any pieces other than equal number of queens and knights. You have to place an equal number of knights and queens on the chessboard such that NO piece attacks any other piece. Each position in the board uses following to represent the status: 0 - no pieces, 1 - queens, 2 - knights.

Given a board with or without any pairs of queen and knight, you have to write a function addMaxPieces which adds as many pairs of queens and knights as possible and returns the updated board in the same format.

You can use the fact that in the best configuration, a maximum of 5 queens and 5 knights can be placed on 8 x 8 board such that NO piece attacks any other piece. An example of such a configuration is given below .

Note that you will get 50% credit, if you add even one extra pair of queen and knight on the board correctly. Instructions to use Open PBT Client:
