Mountain Sequence Pattern
The Mountain Sequence Pattern is a sequence of asterisks (*) arranged in a specific pattern that resembles a mountain. This pattern is formed by incrementing the number of asterisks in each row, starting from one, and then decrementing the number of asterisks until the middle row is reached. After the middle row, the number of asterisks is again incremented until the maximum number is reached.
The goal of this pattern is to create a visual representation of a mountain, where the number of asterisks represents the height of the mountain. The pattern is symmetric, with equal numbers of asterisks on both sides of the mountain.
Example:
Let's take an example to understand the Mountain Sequence Pattern better. Consider the given size of the mountain as 4.
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
In this example, the mountain has a height of 5 rows. Each row is composed of asterisks (*) and spaces. The number of asterisks in each row increases from 1 to 5 and then decreases back to 1, creating a mountain-like shape. The spaces are included to align the asterisks and create the symmetric pattern.
Algorithm:
- Start with the given size of the mountain.
- Set the height of the mountain as a constant value.
- Iterate through each row of the mountain from 0 to the height:
- Iterate through each element in the row from 0 to the given size:
- Include initial spaces to align the elements.
- Display the mountain element (asterisk).
- Include end spaces to align the elements.
- Move to the next line.
- Repeat the above steps for all test cases.
Pseudocode
mountainSequence(n)
if n <= 0
return
height = 5
for i = 0 to height
for j = 0 to n
includeSpace(height - i)
includeStar(i)
includeSpace(height - i)
print newline
end
includeSpace(n)
for i = 0 to n
print space
end
includeStar(n)
for i = 0 to n
print asterisk followed by space
end
Code Solution
Here given code implementation process.
// C program for
// Mountain Sequence Pattern
#include <stdio.h>
// Include n space
void includeSpace(int n)
{
for (int i = 0; i < n; ++i)
{
printf(" ");
}
}
// Include n star with space
void includeStar(int n)
{
for (int i = 0; i < n; ++i)
{
printf("* ");
}
}
void mountainSequence(int n)
{
if (n <= 0)
{
return;
}
int height = 5;
printf("\n Given Size : %d \n", n);
// Outer loop is executing in through by mountain height
for (int i = 0; i <= height; ++i)
{
// Inner loop is executing in through by 0..n
for (int j = 0; j < n; ++j)
{
// Include initial space
includeSpace(height - i);
// Display the mountain element

Time Complexity:
The time complexity of the Mountain Sequence Pattern code is O(height * n), where height is a constant value (5) and n is the given size of the mountain. The nested loops iterate through all the elements in each row, which is proportional to the height and the size of the mountain.
Resultant Output:
The provided code generates the Mountain Sequence Pattern for different test cases. Here are the outputs for the given sizes:
Given Size: 1
* * * * * * * * * * * * * * *
Given Size: 2
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
Given Size: 4
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
Given Size: 3
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
The output demonstrates the Mountain Sequence Pattern for different sizes of the mountain, showcasing the increment and decrement of asterisks in each row, creating the mountain-like shape.
