Attached is the diagram of RISC$-$V pipeline with equality testing being moved to ID stage to optimize branch hazard.

Show the number of stalls for the following two cases.

$1.$ sub x$10,$ x$11,$ x$12$

beq x$10,$ x$15,$ LABEL

$2.$ lw x$5,32($x$6)$

beq x$10,$ x$5,$ LABEL

Modify the above diagram to add necessary forward lines to handle these two cases.
