Question $1-$ Write a function that takes incidence matrix representation of a graph and returns its edge node listing representation $($describe representations clearly$)$

$\backslash$table$[[,1,2,3,4,5,6],[1,1,1,1,0,0,0],[3,0,0,1,1,0,1],[4,0,0,0,1,1,0],[,1,1,0,0,1,0]]$

$E=\left[\begin{array}{cc}1& 4\\ 1& 4\\ 1& 2\\ 2& 3\\ 3& 4\\ 2& 2\end{array}\right]=4$
