Write Intel 8086 assembly programs - use the NASM assembler

Write a program called COUNT to count the number of characters in a null-terminated ASCII string that are equal to a KEY. The
KEY is stored in memory location 0x0150. The string is stored in memory beginning at address 0x0160. Store the 8-bit count in
memory location 0x0154. (Assume the maximum count is 255.)
