Output: 4
Explanation: The last word is “moon” with length 4.
2.Write a python program to print the cube of all numbers from 1 to a given number.
3.Write a Python program to count the number of characters (character frequency) in a string.
Sample String : googlecom
Expected Result : {‘g’: 2, ‘o’: 3, ‘l’: 1, ‘e’: 1, ‘c’: 1, ‘m’: 1}
4. Write a Python program to get a string made of the first 2 and last 2 characters of a given string. If the string length is less than 2, return the empty string instead.
Sample String : ‘hello’
Expected Result : ‘helo’
Sample String : ‘w3’
Expected Result : ‘w3w3’
Sample String : ’ w’
Expected Result : Empty String
