Question

Given String 1="Exam 2021".Give output of string1[-1::-1]

Answer 1

Answer:

hello

Explanation:

String1="Exam2021" # here u have assigned the value of string1  

String1[-1::-1]  #this statement is using the concept of indexing.

"   [-1::-1] means the start value should be -1,stop value is not mentioned that means it will be till the end from wherever it has started and step value is -1 that means we have to move in the opposite direction of the start value   "

now applying index:

character  -  forward indexing  -  reverse indexing

E                -                0               -           (-8)

x                -                 1                -           (-7)

a                -                 2               -            (-6)

m               -                 3               -            (-5)

2                -                 4               -            (-4)

0                -                 5               -            (-3)

2                 -                6               -             (-2)

1                  -                 7               -            (-1)
