Find some X^2 - Y^2 equal to a given Z
0
Request input (Z) from user, -65535<=Z<=65535. Check if (X^2)-(Y^2)=Z (while 0<=X,Y<=1000).
I wrote a code which will receive Z from user, if it's negative, store the negative value and continue as if Z is positive. Two loops, one which will check Y from 0-1000, after that add 1 to X and continue, until both X and Y are 1000 (meaning no answer) or until an answer is found. If Z contained a negative value, exchange X and Y after answer is found.
Would love to see some reviews.
