a) Convert the following code segment into TAC and identify the leader, block and also give its flow graph representation. while(v2v3=v3v2; v2=v2+1; v4=v4v3; while (v430) \{break;\} v2=v2v4; \} v1=v1+1; \} b) Write the equations to analyze reachable definitions and apply it for the above flow graph
