Knight Parade programming to solve the problem: in n rows n columns of the board (such as n = 5), assuming a knight (in chess in the "horse to go on" walking method) from the initial coordinates (x1, y1) starting , to be sung (Parade) board in the position of each of the first. Please compile a program to solve for the Knight Parade "road map" (or tell the knight, starting from a position when not visiting with the board- the problem no solution).
