Question
Write a program to generate and print the given star pattern.Input:The input consists of a single integer N, where 1 ≤ N ≤ 10.Output:Print the star pattern as described.For N=3, the pattern will be * *** ***** *** *
Solution
Sure, here is a step-by-step solution to generate and print the given star pattern:
- Read the value of N from the user.
- Initialize a variable named "rows" with the value of N.
- Initialize a variable named "spaces" with the value of rows - 1.
- Initialize a variable named "stars" with the value of 1.
- Use a loop to iterate through each row from 1 to rows: a. Print spaces number of spaces. b. Print stars number of stars. c. Print spaces number of spaces again. d. Print a new line character to move to the next row. e. Increment the value of stars by 2. f. Decrement the value of spaces by 1.
- Repeat steps 5a to 5f until the loop completes.
- Reverse the process to print the second half of the pattern: a. Decrement the value of stars by 2. b. Increment the value of spaces by 1. c. Repeat steps 5a to 5d until the loop completes.
- End the program.
Here is an example implementation in Python:
N = int(input("Enter the value of N: "))
rows = N
spaces = rows - 1
stars = 1
# Print the first half of the pattern
for i in range(1, rows + 1):
print(" " * spaces, end="")
print("*" * stars, end="")
print(" " * spaces)
stars += 2
spaces -= 1
# Print the second half of the pattern
stars -= 2
spaces += 1
for i in range(1, rows):
print(" " * spaces, end="")
print("*" * stars, end="")
print(" " * spaces)
stars -= 2
spaces += 1
When you run this program and enter the value of N as 3, it will generate and print the star pattern as described:
