Question

The following tasks, in onder Allocate a global array (Le., space in the data segment) enough for storing 4 inegers and initialize the array (from Ist to 4th element) with 8, 1,3 and 2 ot the somse time(ie DONT write sode to put in these values instead). Display a labeled output about the array's initial contents (from Ist to 4th clement) IMPORTANT You are to load the values of the array elements froem memory and use those values to generate dhe labeled output (You are not to simply display a hard-coded, preset string.) Re-order the values in the array so that the contents of the arraymemory (from 1 t to 4th elemen becomes 2 3 , and g using the following operations (in order Swap the coetents in memory of the Ist and 4th elements of the aray Swap the contents in memory of the 2nd and 3ed elements of the array IMPORTANT each of the two swap operations above, you can re-ase (where expedient) the aray's base address in registcr (loaded whom performing the display of the array's initial contents) but you MUST re-load rom mrmory (ie , assuming no km alea ge that certain values might have alreaby exited in some fegistersdee to proe operat ons). she associated arra y elements esh he va we5 Display a labeled output about the arrays contents (from 4t toit element) afer be 2 swapping operatin. abot NOTE: It is from 4th to 1st element and not from 1st to 4th element IMPORTANT Similar to when performing the two swap operations above, you can re-use (where expedient) the array's base address in register (oaded when perfoerming the prior operations) but you MUSI re-lovad the vaes of the array elements fresh from Mmory (.e, assuming no knowledge that certain values might have already existod in some registers due to prior operations
