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 '-'.

Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).Output

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

For example, if the given 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 the output should be "16-25-20-8-15-14".

We need exact output when the code was run

Given a string, write a program to mirror the characters of the string in alphabetical order to create a secret message.

Note: Mirroring the characters in alphabetical order replacing the letters 'a' with 'z', 'b' with 'y', ... , 'z' with 'a'.

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

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

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).Output

All characters in the output should be in lower case.

Explanation

if the given input is "python", "p" should replaced with "k", similarly "y" with "b", "t" with "g", "h" with "s", "o" with "l", "n" with "m". So the output should be "kbgslm".

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.Input

The first line of input will contain two space-separated integers, denoting the M and N.

The next M following lines will contain N space-separated integers, denoting the elements of each list.Output

The output should be M lines containing the ordered matrix.

Note: There is a space at the end of each line.Explanation

For example, if the given M is 3 and N is 3, read the inputs in the next three lines if the numbers given in the next three lines are the following.

1 20 3
30 10 2
5 11 15

By ordering all the elements of the matrix in increasing order, the ordered matrix should be

1 2 3
5 10 11
15 20 30

Sample Input 1 :

3 3

1 20 3

30 10 2

5 11 15

Sample Output 1 :

1 2 3

5 10 11

15 20 30

Sample Input 2 :

88 17 38 72 -10

Sample Output 2 :

-50 -20 -10 3 17

Write a program to print the count of all possible unique combinations of numbers whose sum is equal to K

Write a program to replace elements with zeros

Write a program to find the minimum number of notes required for the amount M. Available note denominations are 500, 50, 10, 1.

Given

M = 1543, it can be written as1543 = 3*(500) + 3*(50) + 0*(10) + 1*(3)Then the output should be

500: 3 50: 0 10: 4 1: 3

sample input=1543 output is 500: 3 50: 0 10: 4 1: 3

sample input is=1259 and output is 500: 2 50: 5 10: 0 1: 9

Encapsulate the following Python code from Section 7.5 in a function named my_sqrt that takes a as a parameter, chooses a starting value for x, and returns an estimate of the square root of a. 

while True:

   y = (x + a/x) / 2.0

   if y == x:

     break

   x = y
