c++ - BFS On a Bipartite graph; Shortest Path between two points -


here's assumption i'm making, before started, tell me if wrong:

  • representing bipartite graph (shown below): can nxm matrix n 1 side , m other , there's 1 @ index if connected, correct?

enter image description here

anyways, i'm trying represent "erdos" number kind of thing, or "kevin bacon number" kind of thing, 1 side movies , other side actors. far have 2 vectors hold each movie , actor , adjacency matrix matrix of nodes (each nodes contains movie name, actor name, , adjacency boolean/number), 1 if actor in movie , 0 otherwise:

enter image description here

i want figure out how many degrees of separation there between 2 actors (i.e. if actor in movie 1, actor b in movie 1 , 2, , actor c in movie 2, degrees between , c 2; 0 if same actor).

my questions are, doing right far? how continue? know bfs uses queue can't seem right, or start on right path. compare? it's know can't seem think of @ all. have 2 functions give me index of requested actor in actors vector (and 1 movie), give me row , column indices of adjacency matrix vector, in order see node @ index.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
