A set of 10 signed data bytes is available in memory starting at 3050H. Write a program to identify the negative numbers. The positive numbers are to be rejected and the negative numbers are to be converted to BCD. The codes for displaying decimal digits using a seven segment display are available in a look-up table in memory starting at 3090H. Use this look-up table to display the BCD numbers obtained after converting the negative numbers to BCD. The digits are to be displayed on seven segment displays connected to ports with addresses 01H, 02H and 03H.
