Print Z pattern
In this article, we will discuss how to print a Z pattern using a C program. We'll explain the problem statement, provide an explanation with suitable examples, present the algorithm and pseudocode, and finally, explain the output with time complexity of the code.
Problem Statement
The problem is to write a program that prints a Z pattern of asterisks based on the given size. The size represents the height of the Z pattern, and each line of the pattern consists of asterisks (*) and spaces ( ).
Explanation with Examples
Let's understand the problem with some examples. Consider the following:
Example 1:
Size: 5
* * * * *
*
*
*
* * * * *
Example 2:
Size: 7
* * * * * * *
*
*
*
*
*
* * * * * * *
Example 3:
Size: 3
* * * * * * *
Example 4:
Size: 9
* * * * * * * * *
*
*
*
*
*
*
*
* * * * * * * * *
In the examples above, we can observe that the Z pattern is formed using asterisks. The first and last lines contain a row of asterisks equal to the size minus one. The middle lines contain spaces to align the subsequent asterisk.
Algorithm and Pseudocode
To print the Z pattern, we can follow the following algorithm:
- Define a function to display spaces. This function takes an integer size as input.
- Inside the space() function, iterate from 0 to size and print a space character.
- Define a function to display asterisks. This function takes an integer size as input.
- Inside the display_star() function, iterate from 0 to size and print an asterisk followed by a space.
- Define the main function.
- Inside the main function, define a function called show_z() that takes an integer size as input.
- If the size is less than 2, return from the show_z() function.
- Print the value of size.
- Initialize a variable called side with the value of ((size-1)*2).
- Use a loop to print the Z pattern:
- If the current iteration is the first or last line, call the display_star() function with size-1 as the argument.
- Otherwise, call the space() function with the side value as the argument.
- Print an asterisk (*) on each line.
- Decrease the value of side by 2 in each iteration.
- Print a newline character.
- In the main function, call the show_z() function with different test cases to demonstrate the pattern.
- Return 0 to indicate successful execution of the program.
The pseudocode for the given algorithm can be written as follows:
function space(size):
for i = 0 to size:
print " "
function display_star(size):
for i = 0 to size:
print "* "
function show_z(size):
if size < 2:
return
print "Size: " + size + "\n\n"
side = (size-1)*2
for i = 0 to size:
if i == 0 or i == size-1:
display_star(size-1)
else:
space(side)
print "*"
print "\n"
side = side - 2
main:
show_z(5)
show_z(7)
show_z(3)
show_z(9)
return 0

{

{

}
}
void show_z(int size)
{
if(size < 2 )
{
return;
}
printf("Size : %d\n\n",size );
int side = ((size-1)*2);
//Display Z pattern of given size
for (int i = 0; i < size; i++)
{
if(i == 0 || i == size-1)
{
display_star(size-1);
}
else
{
space(side);
}
printf("*");
printf("\n");
side-=2;

The output matches the expected Z pattern for each test case. The pattern is printed based on the given size, and the asterisks (*) are arranged in the shape of a Z.
Time Complexity
The time complexity of the code is O(size), where size is the input parameter representing the height of the Z pattern. The code iterates over the size to print each line of the pattern. Therefore, the time complexity is linearly proportional to the size.
