Printing Left Half Pyramid Of Stars

Introduction

Creating patterns with stars is a common exercise in programming. In this article, we will focus on printing a left half pyramid of stars using java. We will discuss the understanding of the pattern, the approach to constructing it, and provide a step-by-step solution with sample code.

Understanding the Left Half Pyramid of Stars

A left half pyramid is a pattern that consists of rows of stars, where each row contains one more star than the previous row. The stars are aligned to the right, forming a half pyramid-like shape.

Approach

To print a left half pyramid of stars, we can follow the following approach:

1. Determine the number of rows in the pattern based on the desired size.

2. Use nested loops to iterate through the rows and columns.

3. Print the desired number of spaces followed by stars in each row, aligning them to the left.

Step-by-Step Solution

1. Input the desired number of rows for the left half pyramid pattern.

2. Use a loop to iterate through each row from 1 to the desired number of rows: 

a. Use another loop to print the spaces before the stars. 

b. Print the desired number of spaces. 

c. Use another loop to print the stars. 

d. Print a star for each column up to the current row number.

3. After printing all the rows, the left half pyramid pattern will be displayed.

Code

Here's an example implementation for printing a left half pyramid of stars:
