comment XOR of Binary Numbers to Reach a Given Number
Thank You! That was really helpful :) I was able to implement the algorithm in C++ based on your input.

comment XOR of Binary Numbers to Reach a Given Number
I tried reducing the matrix to a row echelon form. But with the modulo 2 arithmetic operations, the row echelon form seems to be unreachable. (eg) if the set S = {0010, 1001, 1010, 0101, 1110, 1100 } and X = {0001}, how do I follow the reduction procedure ? I have to develop a c++ implementation for a 1000x200 matrix.

Thank You! Can I get a reference link on how to find whether the augmented matrix is solvable ? The size of the set S can be upto 1000. I just need to find whether a solution exists or not.

@DrKW : Sorry there must be a typo. This expression is a reduced form of another expression. Must have made a typo in that. The value for n=9 is 1332.
