[Verse 1] Meet Sarah, network engineer, she's got a problem here Thousands of computers need connecting, crystal clear She starts at one location, spreads out level by level Breadth-first search explores each neighbor, never gonna settle Like ripples in a pond, expanding circle wide Visits every node at distance one before moving to the side Queue keeps track of order, first in and first out Finding shortest paths when weights are equal, no doubt [Chorus] Graph algorithms, showing us the way Through the maze of data, every single day Breadth-first and depth-first, each one has its place Dijkstra finds the shortest, spanning trees embrace The connections that we're building, strong and running free Graph algorithms, that's our destiny [Verse 2] Now depth-first takes a different route, diving deep instead Like exploring a cave system, following each thread Stack keeps track of where we've been, backtracking when we're done Goes as far as possible before another path's begun Perfect for detecting cycles, or dependency trees Topological sorting, brings structure with such ease Sarah uses this for scheduling, tasks that must align Making sure prerequisites come first, every single time [Chorus] Graph algorithms, showing us the way Through the maze of data, every single day Breadth-first and depth-first, each one has its place Dijkstra finds the shortest, spanning trees embrace The connections that we're building, strong and running free Graph algorithms, that's our destiny [Bridge] But what if roads have different costs, some highways, some dirt tracks? Dijkstra's algorithm finds the cheapest path that never looks back Priority queue guides the way, always choosing least expense Greedy choice at every step, the logic's so immense And for Sarah's network cables, she needs minimum cost to span Kruskal sorts all edges up, connects without a plan For cycles, Prim grows tree by tree, adding closest every time Both create the backbone strong, efficiency in rhyme [Verse 3] From social networks mapping friends, to GPS in your phone Package routing through the web, these patterns have grown Sarah's network now complete, efficient and so clean Graph algorithms made it work, like nothing she's seen Dependencies in software builds, or finding shortest flight These tools solve the problems that keep us up at night [Chorus] Graph algorithms, showing us the way Through the maze of data, every single day Breadth-first and depth-first, each one has its place Dijkstra finds the shortest, spanning trees embrace The connections that we're building, strong and running free Graph algorithms, that's our destiny [Outro] So remember Sarah's story, when networks come alive Graph algorithms power through, help systems truly thrive From searching to connecting, finding paths that shine These algorithms guide us through, every single time
