Count number of ways to jump to reach end | Function to count ways to jump to reach end for each array element.
count_jump [ i ] store number of ways arr [ i ] can reach to the end.
Last element does not require to jump . Count ways to jump for remaining elements.
if the element can directly jump to the end.
Add the count of all the elements that can reach to end and arr [ i ] can reach to them.
if element can reach to end then add its count to count_jump [ i ].
if arr [ i ] cannot reach to the end.
print count_jump for each array element.
