Create an HLA function that loops through a single string argument and verifies that last character found in the string is a capital Z$.$ This function should have the following signature:

procedure endsWithZ$($ stringData : dword $)$; @nodisplay; @noframe;

This function should return into EAX an int$32$ value which is either true or false, $1$ or $0.$ To receive full credit, your endsWithZ$()$ function must not allocate any storage.

You must use the utility functions gets and puts provided here Download hereby downloading this file. Unzip it to find the $.$hla file inside. These are the some of the same routines you used in Unit $15.$ Once you acquire the file, you can include it in your code by saying: #include$("$cs$17$string.hla" $)$;

Your function should replicate the following C code:

bool endsWithZ$($ char $*$ stringData $)$

$\{$

int i $=0$;

char letter $=$;

while $($ stringData$[$ i $]!=$ NULL $)$

$\{$

$//$ loop the last character

letter $=$ stringData$[$ i $]$;

i $=$ i $+1$;

$\}$

return$($ letter $==$Z$)$;

$\}$

IN ORDER TO RECEIVE FULL CREDIT, YOU MUST USE THE TEMPLATE SOLUTION SHOWN BELOW. Of course, you will need to add code to the function to implement the desired algorithm explained above. In addition, you will need to push the parameters to the function.
