#$4$ Examine the following code to method xyz:

Precondition: assume n $=$ hi$,$ and A is an array indexed $1..$ hi

bool xyx$($A$,$ hi$)\{$

int n $=$ hi

int c $=$ n$/2$

for $($i $=$ lo; i $<=$ c; i$++)\{$

if $($A$[$i$]<=$ A$[$i$*2])$

return false;

if $(!($i$*2+1>$ hi$))$

if $($A$[$i$]<=$ A$[$i$*2+1])$

return false;

$\}$

return true;

$\}$

$($a$)$Explain clearly what a true return value from method xyz means.
