Answer 1

Answer:

2) -1

Explanation:

Indexing is the process of assigning index numbers to the elements of array.

It can be done in two ways:

• Forward indexing begins with 0 and ends at n-1 where n is the length on the array.

As for example,

"abcd"

a is at index 0 and d is at index (4-1)=3

• Backward indexing begins with -1 and ends at -n.

d in the string above is at index -1 and a is at -4.
