[3 pts] Use the following program fragment for questions (a)-(e) below w.x; if (m> 0) // node 1 W++node 2 else w 2*w node 3 // node 4 (no executable statement) if (y 10) x-5*y node 5 else x-3*y+5; I node 6 z w+x;node 7 Draw a control flow graph for this program fragment. Use the node numbers given above. Which nodes have defs for variable w? Which nodes have uses for variable w? Are there any du-paths with respect to variable w from node 1 to node 7? If not, explain why not. If any exist, show one. a. b. c. d. e. Eumcrat he dra for variablesw andx
