Calculate the sum of series of numbers

Statement: Calculate the sum of series of numbers. The length of the series is in memory location 4200H and the series begins from memory location 4201H.
a. Consider the sum to be 8 bit number. So, ignore carries. Store the sum at memory location 4300H.
b. Consider the sum to be 16 bit number. Store the sum at memory locations 4300H and 4301H.
Sample problem 1:
4200H  = 04H
4201H  = 10H
4202H  = 45H
4203H  = 33H
4204H  = 22H
Result = 10 +41 + 30 + 12 =  H
4300H  =  H
