Djkstra algorithm (single source Shortest path) The basic idea of the algorithm is to find the closest vertex of the source point (the source point of the above example is the vertex of number 1th) each time, and then extend the vertex as

1, the use of ++i (take A=++i, i=2 as an example)The I value is first added to 1 (that is, i=i+1) and then assigned to the variable a (that is, a=i),Then the final a value is equal to 3, and the I value equals 3.So a=++i equivalent to i=i+1, a=i2,
