Solution:

Step 1: Move bytes from location 10 till the end of array by four bytes downwards.

Step 2: Insert four bytes at locations 10, 11, 12 and 13.

Source program :

• LXI H, 2l31H : Initialize pointer at the last location of array.
• LXI D, 2l35H : Initialize another pointer to point the last location of array after insertion.
• AGAIN: MOV A, M : Get the character
• STAX D : Store at the new location
• DCX D : Decrement destination pointer
• DCX H : Decrement source pointer
• MOV A, L : [check whether desired
• CPI 05H  bytes are shifted or not]
• JNZ AGAIN : if not repeat the process
• INX H : adjust the memory pointer
• LXI D, 2200H : Initialize the memory pointer to point the string to be inserted
• REPE: LDAX D : Get the character
• MOV M, A : Store it in the array
• INX D : Increment source pointer
• INX H  : Increment destination pointer
• MOV A, E : [Check whether the 4 bytes
• CPI 04     are inserted]
• JNZ REPE  : if not repeat the process
• HLT : stop
