Start Process  AssignmentExpression and VariableDeclarator like:
AssignmentExpression Source: j = j + i1 Var Name: j =
        89 Source: j + i1 Op: +
         89 Source: j
         89 Source: i1

VariableDeclarator Source: m=k*AddNumbers(k,4) Var Name: m =
      39 Source: k*AddNumbers(k,4) Op: *
       39 Source: k
       39 Source: AddNumbers(k,4) Op:
        39 Source: AddNumbers Op:
         39 Source: k
         39 Source: 4
