🔥 Optimized Master Thumbnail Prompt (Updated)

Create a high-quality, eye-catching YouTube thumbnail for a beginner-friendly coding tutorial.

Background: A sleek, dark gradient (navy blue to black or deep purple) with subtle programming visuals like binary code, curly braces {}, code snippets, or a matrix-style effect.

Main Text (Large, Centered):
➤ "[TOPIC]" in bold, futuristic white and yellow font with a slight glow or shadow to make it pop.

Subtext (Smaller, Bottom or Corner):
➤ "DSA Basics | NexGenStudioDev" in modern tech font, slightly italicized.

Visual Elements:
– A cartoon or 3D-style coder character with a laptop
– Programming icons (like </>, question marks, numbers, sigma symbol Σ, etc.)
– Optional: floating numbers (1, 2, 3...) or logic symbols (+, %, ==)

Style: Clean, modern, slightly futuristic. Should feel educational but engaging — suitable for a tech YouTube channel focused on DSA and beginner-friendly coding problems.
