comment Solving an $n\times m $ linear system exactly
In my problem $m=O(n^2)$. So, the running time should be $O(n^4)$?

comment Solving an $n\times m $ linear system exactly
Thanks for your comment. What do you mean by exact values of entries? Is this typo? [and then multiplying by Q]. Shouldn't be $\tr(A)$. Any reference paper or lecture note would be appreciated.

n is max{n,m}. Right?

Some entries are integer ranged between 0,-1,1 and the other entries are rational.
