What is the output?

count $=0$

while count $<mtext></mtext><mn>3</mn>$:

print$(\text{'}$loop$\text{'})$

count $=$ count $+1$

print$($f$\text{'}$Final value of count: $\{$count$\}\text{'})$

Prints 'loop' three times, then 'final value of count: $3\text{'}$

Prints 'loop' once, then 'final value of count: $1\text{'}$

Prints 'loop' forever $($infinite loop$)$

Prints 'loop' three times, then 'final value of count: $4\text{'}$
