a

$1.$ a is a list of 'int'

$2.$ Length of list a is NOT known. YOU CANNOT CALL len$($a$)$

$3.$ If the length of the list is $6($as shown above$)$

the content of the array is guaranteed to be between $0$ to $5.$

THERE IS NO REPETATION of numbers

a $=[5,1,0,4,2,3]$;

int h $=$ hop$($a$,3)$;

Your task is to find the number of hops to get $3,$ which is defined as follows:

The top level call is as follows:

a$[3]=4$

a$[4]=2$

a$[2]=0$

a$[0]=5$

a$[5]=3$

h $=$ Number of hop is $=4$

You start from a$[$x$],$ in this case x $=3,$ a$[3]=4,$ and keep looping

until you get x$,$ which is $3.$ The number of times you hoped, in this example, is h $=4.$

One way, to write, using while loop is:

Now write "hop" subroutine as follows:

$1.$ You cannot change interface of hop function

$2.$ You cannot use global$/$static variables

$3.$ You cannot use any loop statements

like while, do$,$ for and goto

$4.$ You cannot call any function except $\_$hop

$5.$ Your code should not be more than $10$ lines
