Shortest path with alternating colors

SpletAn alternating shortest path is a path that is both shortest (among all possible paths) and alternating. Design an algorithm that takes as input a graph G = (V, E,c), where e stores the edge colors, and a start vertex 8 € V. For each vertex t, your algorithm should determine if there exists an alternating shortest path from s to t.

Shortest walk with alternating colors in a directed graph

SpletAlternating turns, each one chooses a number from the set f1;3;4gand removes exactly that number of sticks from the pile (so if the pile only has 2 sticks remaining the next player must take 1). The winner is the player who takes the last stick. For 1 k 100, determine the number of cases in which the •rst player can guarantee that he will win.
