Consider the following pseudocode function?

int f$($int n$)$

int x $0$

int value $-1$

while $($x $<=$ n$)$

x $$ x $+5$

value $$ value $+1$

end while

return value

end f

if the input is a non$-$ negative integer n$,$ what is the output of the function $?$ floor and celing function denote the floor and celing function respectively?

A$.$ floor$($n$/5)$

B$.$ Ceiling $($n$/5)$
