Answer:

import random

print("Hello! I have a random number from 1 to 100! It is your job to try and guess it!")

number = random.randint(1,101)

guess = int(input("start to guess: "))

num_guesses = 1

while guess != number:

if guess > number:

print("lower")

guess = int(input("try again: "))

num_guesses +=1

elif guess < number:

print ("higher")

guess = int(input("start to guess: "))

num_guesses +=1

print("congrats it took you", num_guesses, "tries")

1.1. (30 points) Write a program to calculate the average number of cars sold by a car agency over a period of years for the fir

mario62 [17]

Answer:

count = 0

months = 0

years = int(input("Enter the number of years: "))

for year in range(1, years+1):

cars_sold = int(input("Enter the number of cars sold in first six months: "))

count += cars_sold

months += 6

print("Number of months: " + str(months))

print("Number of cars sold in total: " + str(count))

print("Average number of cars sold per month: " + str(count / months))

Explanation:

Initialize the variables

Ask the user for the number of years

Create a for loop that iterates depending on the given number of years

Ask the user for the number of cars sold in the first six months of the year

Increment the count by given number and increment the months by 6 after each iteration

Print the months, count and, average

A sinewave has a period (duration of one cycle) of 645 μs. What is the corresponding frequency of this sinewave, in kHz, express

irga5000 [103]

The corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures is: <em>155 kHz.</em>

<u>Given the following data:</u>

Period = 645 μs

Note: μs represents microseconds.

<u>Conversion:</u>

1 μs = $1$ × $10^{-6}$ seconds

645 μs = $645$ × $10^{-6}$ seconds

To find corresponding frequency of this sinewave, in kHz;

Mathematically, the frequency of a waveform is calculated by using the formula;

$Frequency = \frac{1}{Period}$

Substituting the value into the formula, we have;

$Frequency = \frac{1}{645\; * \;10^{-6}}$

Frequency = 1550.39 Hz

Next, we would convert the value of frequency in hertz (Hz) to Kilohertz (kHz);

<u>Conversion:</u>

1 hertz = 0.001 kilohertz

1550.3876 hertz = X kilohertz

Cross-multiplying, we have;

X = $0.001$ × $1550.39$

X = 155039 kHz

To 3 significant figures;

<em>Frequency = 155 kHz</em>

3. (20 points) Write a C++ recursive function that finds the maximum value in an array (or vector) of integers without using any

Luden [163]

Answer:

Following are the code to this question:

In option (i):

#include <iostream>//defining header file

using namespace std;

int findMax(int B[], int x)//defining recursive method findMax

{

if (x == 1)//defining condition when value of n==1

return B[0];//return array first element

return max(B[x-1], findMax(B, x-1)); // calling recursive method inside max method and return value

}

int main() //defining main method

{

int B[] = {12, 24, 55, 60, 50, 30, 29};//defining array B

int x= 7;//defining integer variable and assign a value

cout << "Maximum element value of the array is: "<<findMax(B, x)<<endl;//calling method findMax and print value

return 0;

}

Output:

Maximum element value of the array is: 60

In option (ii):

$\Rightarrow \ T(n) = 1 + T(n-1)\\\Rightarrow 1 + 1 + T(n-2)\\ \Rightarrow 1 + 1 + 1 + ... n \ times \\\Rightarrow O(n) \\$

Explanation:

In the above-given program a recursive method "findMax" is defined, which accepts an array "B" and an integer variable "n" in its parameter, inside the method a conditional statement is used that, checks value of x equal to 1.

If the above condition is true it will return the first element of the array and find the max number.
Inside the main method, an array B is declared that assigns some values and an integer variable is declared, that also assigns some values, in the last step print method is used that pass value in method and prints its return value.
In the option (ii) we calculate the Big-O notation algorithm value.
