Three cargo crates, PPP, QQQ, and RRR, are arranged on three platforms at a shipping dock as shown below.
The command MOVE(X, Y) relocates the single top crate from Platform X to the top of any crates already stacked on Platform Y.
State the final arrangement of the crates on Platform A, Platform B, and Platform C after the following algorithm is executed:
MOVE(B, C)
MOVE(B, A)
MOVE(C, A)
Your answer should clearly indicate which crates are on each platform, specifying the bottom-to-top order for any platform containing more than one crate.
