If [ ] denotes the greatest integer less than or equal to the real number under consideration, and $-1\le \mathrm{x}<0,0\le \mathrm{y}<1$,$1\le \mathrm{z}<2$, then the value of the determinant $\left|\begin{array}{ccc}\left[\mathrm{x}\right]+1& \left[\mathrm{y}\right]& \left[\mathrm{z}\right]\\ \left[\mathrm{x}\right]& \left[\mathrm{y}\right]+1& \left[\mathrm{z}\right]\\ \left[\mathrm{x}\right]& \left[\mathrm{y}\right]& \left[\mathrm{z}\right]+1\end{array}\right|$ is
