Write a program to print the following, Given a word W and pattern P, you need to check whether the pattern matches the given word.The word will only contain letters(can be Uppercase and Lowercase). The pattern can contain letters, ? and *.
? : Can be matched with any single letter.
* : Can be matched with any sequence of letters (including an empty sequence).
If the pattern matches with the given word, print True else False.

- You are a Geneticist employed by Thato Biotech Pty Ltd in a criminal case, which could not be solved due to the integrity of DNA used as evidence. You are requested to ascertain the integrity of DNA evidence. You decided to resuspend the purified DNA in a volume of 100uL of double-distilled nuclease-free sterile water. You then diluted 10uL of the DNA sample to a total volume of 100uL with water quality for spectrophotometric analyses. On measuring the absorbance of this diluted sample at 230, 260, and 280nm she obtained the following readings:
A280nm= 0.494; A260nm = 0.364; A230nm= 0.191
a) What is the DNA concentration of the 100uL aliquot, in 3 significant figures
b) How much total DNA was purified by the procedure?
c) Is this DNA pure? If yes, how do you know? if not, what is the most likely contaminant?
d) if this DNA was contaminated with salts what would you expect in the absorbance readings?
e) If DNA was contaminated with RNA, how would you purify your DNA?
Write a program to print the following output.
Input
The first line contains a string.
The second line contains some space-separated strings.
Output
The output should be a single integer.
Explanation
scramble word = "tacren"
guessed words = ["trance", "recant"]
Since "trance" and "recant" both have length 6 then you score 54 pts each.
So the output is 108.
Sample Input1

trance recant
Sample Output1
108

Write a python program to print the following output.
Input
The first line of input contains a single line positive integer N.
The second line of input contains a space-separated integers denoting the cost of the item.
Output
The output is a single line integer.
Explanation
For example, Given N = 2 and cost = 10 200
Ram has to pay for both the items, he won't get anything for free.
So the output is 210.

2 In a medical study, patients are classified in 8
ways according to whether they have blood type AB+,
AB−, A+, A−, B+, B−, O+, or O−, and also according to whether their blood pressure is low, normal, or
high. Find the number of ways in which a patient can
be classified.
Python Problem Solving
You're given a positive integer: Perform the sequence of operations as per below guidelines until the value reaches 1:
If N is even --> N / 2
If N is odd --> N * 3 + 1
Print the total number of steps it took to reach 1.
Input
The first line of input contains an integer.
Output
The output should be a single integer denoting the total number of steps.
Explanation
For Example, using N = 10 as the input, with 6 steps.
10 is even - 10/2 = 5
5 is odd - 5 * 3 + 1 = 16
16 is even - 16 / 2 = 8
8 is even - 8 /2 = 4
4 is even - 4/2 = 2
2 is even - 2/2 = 1 --> Reached 1.
So the output should be 6.
