$1$ RSA

$($RSA$)$ Alice uses Bob's public key $(443,2537)$ to encode a message $($using the encoding

scheme below.$)$ If $2537=43*59,$ and Alice sends $"08620759",$ when Bob decodes it

what does he get?

Assume encoding is done by using one key $($i$.$e$.$ either $S_A,$ or $P_A,$ or $S_B,$ or $P_B).$
