Given the following code, what type of sort does it perform?

void sort$($int arr$[])\{$

int $n=$ arr. length;

for $($int $)>(arr[j+1])>(arr[j+1]\}$

int temp $=$arr$[j]$;

arr$[j]=$arr$[j+1]$;

arr$[j+1]=$ temp;

$\{))>(arr[j+1]\}$

int temp $=$arr$[j]$;

arr$[j]=$arr$[j+1]$;

arr$[j+1]=$ temp;

$\{\{$
