“First, we define the graph,” Natsu explained, pointing at the code. “Each node is a point in the maze, and each edge is a possible step. The weight of the edge tells us how ‘costly’ it is to move there—think of it like the difficulty of climbing a steep hill versus walking on flat ground.”

She glanced up from her notebook, eyes wide with anticipation. “What are we learning today?”

Natsu smiled, a rare, genuine smile that reached his eyes. “All the time. Every line of code we write is a step on a path we can’t fully see. The important thing is that we keep walking—together.” Layarxxi.pw.Natsu.Igarashi.teaches.his.stepsist...

“Maybe one day,” she whispered, “we’ll make a maze that anyone can walk through, not just in code, but in the real world.”

“This is where art meets science,” Natsu said, his voice low. “We’ll let the program ‘wander’ a bit, just like we do in real life. It makes the journey more interesting, even if it’s not the absolute shortest.” “First, we define the graph,” Natsu explained, pointing

She hesitated only a moment, then pressed Enter . The holographic maze lit up, a bright line tracing a route that twisted and turned, occasionally looping back before finally reaching the glowing exit.

He pulled up a terminal window, his fingers dancing across the keys. Lines of Python unfurled, each variable named after a color in the rainbow— red_node , orange_edge , yellow_weight , and so on. “What are we learning today

Aiko watched, her eyes tracking the syntax like a detective following clues. “So the algorithm looks at all possible paths and picks the one with the lowest total cost?”
