Secret Message - 2

Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.

a b c d e f g h i j k l m n o p q r s t u v w x y z

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

Input

Input will be a string in single line containing spaces and letters both uppercase and lowercase.

Output

Output should be a single line containing secret message. All characters in output should be in lower case.

Explanation

For example, if input is "python", "p" should replaced with "16", similarly"y" with "25","t" with "20","h" with "8","o" with "15","n" with "14". So output be "16-25-20-8-15-14".

Sample Input 1

given a sentence in camel case and want to convert to snake case using for loop and indexing

write a function that takes an array of integers as input and prints the second maximum difference between any two elements from an array in python

Rearrange Numbers in String

Given a string, write a program to re-arrange all the numbers appearing in the string in decreasing order. Note: There will not be any negative numbers or numbers with decimal part.

Input

The input will be a single line containing a string.

Output

The output should be a single line containing the modified string with all the numbers in string re-ordered in decreasing order.

Explanation

For example, if the given string is "I am 5 years and 11 months old", the numbers are 5, 11. Your code should print the sentence after re-ordering the numbers as "I am 11 years and 5 months old".

Sample Input

I am 5 years and 11 months old

Sample Output

I am 11 years and 5 months old

Make a game where the computer will guess a random number for different given ranges eg 1-10, 10-20, 30-20. You are given only 5 lives double digits are allowed like 11. the program must return not a number in the given range if you input anything that isnt in the given range for example 1-10; 1,2,3,4,5,6,7,8,9,10. The program should also ask you if u want to play again
