Staircase

Staircase is a command line application that is built on JAVA 8.

Technology Stack

JAVA8 Eclipse

Unique Features

1. Use stream instead of array so memory usage is optimized. Program can be used for high throughput.
2. Big O is optimized as the complexity is O(n) using:

new char[max_height_value - i]).replace('\0', ' ')
new char[i]).replace('\0', '#')

to generate ' ' or '#' further enhance the performance of application.

3. Streaming means when there is a value on the stream, program tends to execute data though the whole process has not finished yet. This means minimal latency in processing.

Usage

From root folder of this project on command prompt, execute:

java ./src/com/staircase/main.java
