patternproblems

interactive pattern generation engine

multi-threaded CLI engine for generating geometric and numerical ASCII patterns based on user-specified dimensions.

architecture

the engine utilizes a modular Patterns class coupled with multi-threading to handle pattern rendering isolated from the main control loop.

core components

• Patterns.triangle(n) - renders a left-aligned right-angled star triangle of height n.
• Patterns.pyramid(n) - renders a centered, space-padded symmetrical star pyramid.
• Patterns.numberPyramid(n) - renders an ascending numerical pyramid preserving column alignment.
• main() - interactive console loop prompting dimension size, managing execution threads, and handling screen refreshes.

execution

python patterns.py

interactive choices:

1. right-angled star triangle
2. centered star pyramid
3. numerical pyramid
