Write an assembly program in emu8086 that performs the following operations:

1. Load decimal 45 into the accumulator 2. Add hexadecimal 2F to the accumulator 3. Invert every bit in the lower nibble of the sum, but leave the upper nibble unchanged, using a mask. 4. Subtract binary 0001 1100 from the previous result 5. Create another mask using the AND instruction to preserve all bits of the previous result except the least significant 3 bits, which should be cleared. Make sure it runs in emu8086. I'm using version 4.08. Thanks!
