Ascending Order

To write an 8085 assembly language program to arrange the given array 5 data bytes stored in the memory location starting from 8100 in ascending order.
ALGORITHM:
STEP 1: Load the D register with the data 05.
STEP 2: Decrement the content of D register.
STEP 3: Load the C register with the data 05.
STEP 4: Decrement the content of C register.
STEP 5: Load the HL register pair with the address 8100.
STEP 6: Move the data in the location 8100, which is addressed by HL
register pair.
STEP 7: Increment the address of HL register pair.
STEP 8: Move the data from M to B register.
STEP 9: Compare the data in B register with the accumulator.
STEP 10: If there is carry, move the data from M to B register.
STEP 11: Decrement the address of HL register-pair.
STEP 12: Move the data from M to B register.
STEP 13: Increment the address of HL register pair.
STEP 14: Decrement the content of C register.
STEP 15: If count is not equal to zero go to step 6.
STEP 16: Decrement the contents of contents of D register.
STEP 17: Stop the execution.
