Preliminary Test 04


Create a Python function that takes a list of n integers and returns the largest number among the n integers.

The function f(x,y)={x^2y/x^4+y^2 (x,y) is not=0 0, (x,y)=0 is not continuous at (0,0)

Preliminary Test 03


Create a Python function that takes a list and returns a new list with unique elements of the first list.


Sample List: [1,2,3,3,3,3,4,5]


Unique List: [1, 2, 3, 4, 5]

Write a program to print the following,


Input

The first line contains a string representing a scrambled word.

The second line contains some space-separated strings representing words guessed by the player.


Output

The output should be a single integer of the final score.


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

tacren

trance recant


Sample Output1

108

Preliminary Test 01


Create a Python function that takes a number as a parameter and check the number is PRIME or NOT.


Note: A prime number (or a prime) is a natural number greater than 1 and that has no positive divisors other than 1 and itself.

The mean weight of Grade 11 Section Star is 51 kg. and the standard deviation is 3.12 kg. Assuming the weight are normally distributed, what percent of weight greater than 57 kg.?

Student scores on a test that measures self-image are approximately normally distributed. This test is

administered to 20 science students and the mean and standard deviation of their test scores are 88

and 24, respectively.

a) Find a 98 % confidence interval of the true mean.

b) What can we assert with 98% confidence about the possible size of our error if we estimate the

mean score to be 88?
