Suppose the following program was intended to compute the sum of the inputs, where $-1$ is used as the sentinel$.$ Which of the following best describes the bug in this code?

sum $=0$

value $=0$

while value $-1$ :

value $=$ int $($input $("$Enter a value: $"))$

sum $=$ sum $+$ value

print $($sum$)$

A sentinel of $0$ should be used instead.

The variable input shctld have been initialized.

The sentinel should not be included in the sum.

The loop does not terminate when the sentinel is read.
