Q$1\mathrm{.}12(2$ points$)$ Consider the following python code that accepts an array of size n:

def whatami$2($x$)$:

# Create an array of size $4$ with each entry as $""$

tmp $=[""]*4$

for i in len$($x$)$:

if i $==$ len$($tmp$)$:

tmp$2=[""]*(2*$ len$($tmp$))$

for j in len$($tmp$)$:

tmp$2[$j$]=$ tmp$[$j$]$

tmp $=$ tmp$2$

tmp$[$i$]=$ str$($x$[$i$])$

return tmp

The O execution time for the code is:
