You are given the following assembly program, with additional information about the program memory address of each instruction.

Line no$.$ Prog. address $($hex$)$ Label Instruction

$11$D$24$

ldi R$17,-10$

$21$D$25$ ldi R$20,23$

$31$D$26$ call CALC

$41$D$28$ rjmp end

$51$D$29$ SUBT: subi R$20,15$

$61$D$2$A ret

$71$D$2$B CALC: add R$20,$ R$17$

$81$D$2$C call SUBT

$91$D$2$E ret

$101$D$2$F end: rjmp end

When line $5($labeled by SUBT$)$ is executed, what are the top two entries on the stack?
