A small project has $12$ activities – $\text{N, P, Q, R, S, T, U, V, W, X, Y,}$ and $\text{Z}$. The relationship among these activities and the duration of these activities are given in the Table.

$$\begin{array}{|cl|cI|cI|}\hline &\textbf{Activity} & \textbf{Duration} & \textbf{Depends} \\& &\textbf{(in weeks)}&\textbf{upon} \\ \hline &\text{N} & \text{2} & \text{-} \\ \hline &\text{P} & \text{5} & \text{N}\\ \hline &\text{Q} & \text{3} & \text{N} \\ \hline &\text{R} & \text{4} & \text{P} \\ \hline &\text{S} & \text{5} & \text{Q} \\ \hline &\text{T} & \text{8} & \text{R} \\ \hline & \text{U} & \text{7} & \text{R, S} \\ \hline & \text{V} & \text{2} & \text{U} \\ \hline & \text{W} & \text{3} & \text{U} \\ \hline & \text{X} & \text{5} & \text{T, V} \\ \hline & \text{Y} & \text{1} & \text{W} \\ \hline & \text{Z} & \text{3} & \text{X, Y} \\ \hline \end{array}$$

The total float of the activity $\text{“V”}$ (in weeks, in integer) is __________________
