Assume that there are two processes $P_i$ and $P_j$ and the load and store instructions are not reordered. Below is

an algorithm for Process $P_i,$ proposed as a solution to the critical section problem between the two processes

Can it actually be a solution to the critical section problem? If not, explain the reason why.

$($Discuss in terms of one of or all requirements to critical$-$section problems' solution, $1.$ mutual exclusion, $2.$ progress, $3.$ bounded waiting$).$
