Consider the following method:

public a$($String $s$

int $v=0$;

for$($int $x=1$;$x$ s$.$ length; $x=x+1)\{$

if

$v=v+1$

$\}$

$\}$

return $v$;

$\}$

Exactly how many lines of code $($statements$)$ are executed by the method $a()$ in the worst case? Express your answer in terms of $n,$

the length of the string $s.$

Hint: simplify your final answer as much as possible, and do not put spaces in your answer. Use juxtaposition for the multiplication

operator, for example to write "nine times n$"$ write $"9$n$"$ not $"9$xn$"$ or $"9*n"$; to write "four times $(n+2)"$ write $"4($n$+2)",$ not $"4$x$($n$+2)"$

or $"4**(n+2)".$ Do not write your answer in Big$-$O notation. Write the exact number of lines executed.
