For each following, assume the Before values when the given instruction is executed. Give the requested After values.

Notes:

MOVZX adds leading zeroes (0) to fill up the destination storage

MOVSX adds copies of the sign in the source storage as leading values to fill up the destination storage.

XCHG: exchanges the values of the given pair of storage locations.

The Status Flags are set according to the result obtained: ZF: zero flag, SF: sign flag, OF: overflow flag, PF: parity flag
