This is a Progressive programming.It is to be Done on. Emu8086.Please do the all Parts I am posting it for the fifth time no one is completing the whole programming so please do the all 4 ques step by step . Whom will complete this one i will give best review for him/her

SYST26671 Programming Exercise 1. Write an Assembler Program using the Emu8086 that will input a string of upper case letters from the keyboard, store the string in memory, and then display the equivalent lower case letters (Example: inputting ABC, outputting abc) 2. Modify your program above so the input string can contain a combination of both upper and lower case letters and the output will be the string in reverse case. (Example: inputting AbCD, outputting aBcd) 3. Modify your program above so the input string can contain both UPPER and lower case letters and punctuation like commas or spaces. The program should pass any character which is not an upper or lower case letter through unchanged. (Example: Input: Ta,ble T Output: tA, BL;E 4. Modify your program (above) so the output will be the reverse case and also the reverse order. Plus implementing the following alphabet conversion: Original A BCD E Converte G H I JK where the alphabets are shifted 6 letters down (Example: Inputting AbC DeF, outputting: IKj iHg his is a progressive programming assignment, and will be marked as follows
