EX $5\mathrm{.}1$:

In the MinOfThree program, if two or more values are equal, it will still work correctly.

It doesn't matter whether the equal values are lower or higher than the third. The program simply finds the minimum of the three values.

EX $5\mathrm{.}2$: The issue with the provided code is the incorrect use of double minus signs $(--)$ and if statements without braces. Here's the corrected code:

if $($total $==$ MAX$)\{$

if $($total $<$ sum$)\{$

System.out.println$("$total is MAX and $<$ sum."$)$;

$\}$

$\}$ else $\{$

System.out.println$("$total is not equal to MAX"$)$;

$\}$

EX $5\mathrm{.}3$: The provided code snippet appears to be incomplete or has a typo. It won't compile. The word "Tength" seems to be a typo, and the purpose of this code is unclear. If you provide more context or the correct code, I can help you further.

EX $5\mathrm{.}4$: The code is not formatted properly, and there are syntax errors. Here's a corrected version of the code:

int num $=87,$ max $=25$;

if $($num $<$ max $/2)\{$

System.out.println$("$apple$")$;

$\}$

System.out.println$("$orange$")$;

System.out.println$("$pear$")$;

Output: "orange" and "pear" will be printed because the condition num $<$ max $/2$ is not met.

EX $5\mathrm{.}5$: The code contains syntax errors and does not provide expected output. Here's a corrected version:

int num $=100,$ num$1=15,$ num$2=-40$;

if $($num $<$ num$1$ && num $<$ num$2)\{$

System.out.println$("$lemon$")$;

$\}$

System.out.println$("$see$")$;

System.out.println$("$grope$")$;

Output: "lemon" will be printed because the condition num $<$ num$1$ && num $<$ num$2$ is true.

EX $5\mathrm{.}6$: To arrange the list of strings in lexicographic order, you would get:

"book"

"bookkeeper"

"Etho$)"$

"Fred"

"HEPHALUMP"

"Lucy"

"ricky"

$"6789"$

$"100"$

$"12345"$ Consulting the Unicode chart will help you determine the correct order.
