Answer:

The program is as follows:

my_list = []

inp = input()

while inp.lower() != "stop":

my_list.append(int(inp))

inp = input()

Dict_freq = {}

for i in my_list:

if (i in Dict_freq):

Dict_freq[i]+= 1

else:

Dict_freq[i] = 1

for key, value in Dict_freq.items():

print (key,"-",value,"times")

Explanation:

This initializes a list of elements

my_list = []

This gets input for the first element

inp = input()

The following iteration is repeated until user inputs stop --- assume all user inputs are valid

while inp.lower() != "stop":

This appends the input to the list

my_list.append(int(inp))

This gets another input from the user

inp = input()

This creates an empty dictionary

Dict_freq = {}

This iterates through the list

for i in my_list:

This adds each element and the frequency to the list

if (i in Dict_freq):

Dict_freq[i]+= 1

else:

Dict_freq[i] = 1

Iterate through the dictionary

for key, value in Dict_freq.items():

Print the dictionary elements and the frequency

print (key,"-",value,"times")

Pseudocode for mystry algorithm

kari74 [83]

Answer:

Initially if x = a = 2437 and y = 875, condition (1) that is x>y is true and output would be x = 1562 with y = 87

Explanation:

According to pseudo code the code will run until x becomes equal to y. Initially if x = a = 2437 and y = 875, condition (1) that is x>y is true. So next step would be x=x-y and output would be x = 1562 with y = 875. With initial values x = a = 2437 and y = 875, x becomes equal to y after 21 iterations and output is x=y=1

Implement a program that requests the user to enter the x and y coordinates (each between 10 and 10) of a dart and computes whet

igomit [66]

Answer:

Following are the program in the Python Programming Language.

#import math package

from math import sqrt

#define function

def circle(x,y):

#return the square root

return sqrt( (x)**2 + (y)**2 )

#get input from the user

x = float(input("Enter first number between -10 and 10: "))

#get input from the user

y = float(input("Enter first number between -10 and 10: "))

#check condition

if(circle(x,y)<8):

#then, print message

print("It is in!")

#otherwise

else:

#print message

print("It is not in!")

Output:

Enter first number between -10 and 10: 1.5

Enter first number between -10 and 10: 2.6

It is in!

Explanation:

Here, in the following program in the Python Programming Language.

Define the function "circle" and pass the argument "x" and "y" then, return square root of x and y.

Set a variable "x" which get float type input from the user.
Set a variable "y" which get float type input from the user.
Set the if conditional statement to check that the function return the value less than 8 then, print the message.
Otherwise, it print the following message.

Give an example of a function from N to N that is: Hint: try using absolute value, floor, or ceiling for part (b). (a) one-to-on

Naily [24]

Answer:

Let f be a function

a) f(n) = n²

b) f(n) = n/2

c) f(n) = 0

Explanation:

a) f(n) = n²

This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.

Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:

f(a) = f(b) ⇒ a² = b² ⇒ a = b

The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.

b) f(n) = n/2

The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:

f(2n) = [2n/2] = n

The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:

When the value of n=1, then

n/2 = [1/2] = [0.5] = 1

When the value of n=2 then

n/2 = [2/2] = [1] = 1

c) f(n) = 0

The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.
