Answer: $($penalty regime: $0,5,$dots$\%)$Study the examples below and write one function that works exactly like the examples.

For example:

Test Result

result $=$ number$\_$string$($startNumber$=5,$ endNumber$=16,$ separator$="*",$ show$=$"even"$)$

result $=$ number$\_$string$($startNumber$=5,$ endNumber$=16,$ separator$="$#$",$ show$=$"odd"$)$

$6*8*10*12*14*16$

$5$#$7$#$9$#$11$#$13$#$15$

result $=$ number$\_$string$($startNumber$=1,$ endNumber$=9,$ separator$="*",$ show$=$"odd"$)$

result $=$ number$\_$string$($startNumber$=2,$ endNumber$=8,$ separator$="$#$",$ show$=$"even"$)$

$1*3*5*7*9$

$2$#$4$#$6$#$8$
