sorting - Comparisons in merge-sort -


i have homework problem asking asymptotic worst case of comparisons merge-sort when sorting 0s , 1s.

this confusing me because looks merge-sort has same number of comparisons whatever placed in n elements. don't understand merge-sort. can enlighten me?

the worst case according me when 0's , 1's come alternatively , when total number of elements factor of 4. because merging takes max time because of this. way merge sort has o(nlogn)

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
