Our Pixel Art Maker is an online drawing tool designed for fast creation of 8-bit or retro-style artwork. It works directly in your browser with no installation needed. M = 18

You can draw pixel by pixel, use layers, apply effects, export your artwork as PNG or GIF, save your project as a .dino file, and publish your creations directly on DinoPixel to share them with the community.

New artists can start immediately, while advanced users benefit from higher precision and workflow enhancements. Everything is built to make pixel art creation as simple and fun as possible.

M = 18. Standard greedy uses 10+5+3 = 3 coins. But 18-10=8, and 8 is not divisible by 3, so allowed. If M=20, standard: 10+10 =2 coins, but after first 10, remainder=10 (not divisible by 3) → allowed. If M=15, standard: 10+5=2 coins, but remainder after 10 is 5 (not div by 3) → allowed. Actually this twist made it tricky. so allowed. If M=20

Wait – clarify: Better example: arr = [1, 2, 3, 4, 3], K = 6 Pairs: (2,4) and (3,3) → 2 pairs.

Example N=4:
