$1-$ Create a list called $($list$\_1)$ with five different integers entries greater than zero.

$2-$ Then set list$\_2=$ list$\_1$

$3-$ Change list$\_2[1]$ to different entry

$4-$ What happened to list$\_1?$

$5-$ Now set list$\_3=$ list$\_1[$:$]$

$6-$ Change list$\_3[2]$ to different entry

$7-$ What happened to list$\_1?$

$8-$ Now create a function chng$\_$frst$\_$TO$\_$zro$(1)$ that takes a list, sets its first entry to zero, and print the list.

$9-$ Apply the function to all three lists list$\_1,$ list$\_2$ and list$\_3?$

$10-$ What happened to the lists?
