Write MIPS assembly code equivalent to the provided Java code below:

public class Demo $\{$

public static void main$($String$[]$ args$)\{$

String inputString $=$ "Hello World";

char targetChar $=\text{'}$d$\text{'}$;

int count $=$ countOccurrences$($inputString$,$ targetChar$)$;

System.out.println$("$The character $\text{'}"+$ targetChar $+"\text{'}$ appears $"+$ count $+"$ times in the given string."$)$;

$\}$

public static int countOccurrences$($String input, char target$)\{$

int count $=0$ ;

if $($input$.$isEmpty$())\{$

return $0$;

$\}$

if $($input$.$charAt$(0)==$ target$)\{$

count $=1$;

$\}$

count $=$ count $+$ countOccurrences$($input$.$substring$(1),$ target$)$;

return count;

$\}$

$\}$
