Let \(A={-3,-2,-1,0,1,2,3}\) and R be a relation on A defined by \(xRy\) if and only if \(2\mathrm{x}-\mathrm{y}\in {0,1}\). Let \(l\) be the number of elements in R. Let \(m\) and \(n\) be the minimum number of elements required to be added in R to make it reflexive and symmetric relations, respectively. Then \(l+m+n\) is equal to:-
