Answer:
I am writing a Python program:
def Eratosthenes(n):
primeNo = [True for i in range(n+1)] # this is a boolean array
p = 2 # the first prime number is initialized as 2
while (p * p <= n): # enumerates all multiples of p
if (primeNo[p] == True):
for i in range(p * p, n+1, p): #update multiples
primeNo[i] = False
p = p + 1
for p in range(2, n): #display all the prime numbers
if primeNo[p]:
print(p),
def main(): #to take value of n from user and display prime numbers #less than or equal to n by calling Eratosthenes method
n= int(input("Enter an integer n: "))
print("The prime numbers less than or equal to",n, "are: ")
Eratosthenes(n)
main()
Explanation:
The program contains a Boolean type array primeNo that is initialized by True which means that any value i in prime array will be true if i is a prime otherwise it will be false. The while loop keeps enumerating all multiples of p starting from 2, and striking them off from the original array list and for loops keep updating the multiples. This process will continue till the p is greater than n. The last for loop displays all the prime numbers less than or equal to n which is input by user. main() function prompts user to enter the value of integer n and then calls Eratosthenes() function to print all the prime numbers less than or equal to a given integer n.
Answer:
I am writing the Python program:
lyrics = ["I wanna be your endgame", "I wanna be your first string",
"I wanna be your A-Team", "I wanna be your endgame, endgame"]
lines_of_sanity = 6
counter = 0
while counter <= lines_of_sanity+1:
for line in lyrics:
print(line)
counter = counter + 1
print("MAKE IT STOP")
Explanation:
- The lyrics is a list which has the following lines of song.
I wanna be your endgame
I wanna be your first string
I wanna be your A-Team
I wanna be your endgame, endgame
- The value of lines_of_sanity is 6.
- counter variable is initialized to 0.
- The while loop starts which keeps executing until the value of counter becomes greater than 6 which is the value of lines_of_sanity
- The for loop inside the while loop moves through each line of lyrics list and prints that line. The counter variable increments to 1 at each iteration.
- Lets see what the while and for loops print at each iteration:
1st iteration: counter = 0, following line is displayed:
- I wanna be your endgame
- Value of counter increments by 1.
- counter = 1
2nd iteration: counter = 1, following line is displayed:
- I wanna be your first string
- Value of counter increments by 1.
- counter = 2
3rd iteration: counter = 2, following line is displayed:
- I wanna be your A-Team
- Value of counter increments by 1.
- counter = 3
4th iteration: counter = 3, following line is displayed:
- I wanna be your endgame, endgame
- Value of counter increments by 1.
- counter = 4
5th iteration: counter = 4, following line is displayed:
- I wanna be your endgame
- Value of counter increments by 1.
- counter = 5
6th iteration: counter = 5, following line is displayed:
- I wanna be your first string
- Value of counter increments by 1.
- counter = 6
7th iteration: counter = 6, following line is displayed:
- I wanna be your A-Team
- Value of counter increments by 1.
- counter = 7
- The program should keep going to finish out the current verse. So following line is displayed:
- I wanna be your endgame, endgame
- The loop breaks as the value of counter = 7 is greater than lines_of_sanity i.e. 6
- So at last the print("MAKE IT STOP") statement is execute which displays the following line:
- MAKE IT STOP
- The program along with the output is attached.
