Core ideas: 1. Use a dictionary to host the first letter of the element in the Lista and the count of the letter 2. Use Dict.haskey () to determine if the element is in the dictionary:1) exists, value +12) Not present, add a new key value pair3. Sort the dictionary by value.lista=['a','ABC','D','ABC','FGI','ABF']dicta= {} forIinchlista:ifDicta.has_key (i[0]): dicta[i[0]+ = 1Else: dicta[i[0]]= 1PrintSorted (Dicta.items (), key=LambdaX:x[1],rever

Title: Merge sort Python implementation
External sort--merging sort principle
Merge sorting basically merges and sorts two sorted data, and if the data you read is not sorted, you can use other sort methods to process the two data before merging the two sorted data.

Print "Total run time:"
Print time ()-T
The above code will probably need 16.09seconds to run. If the line #list = Dict.fromkeys (list,true) Comment is removed, the list is converted to a dictionary and then run, and the time is approximately 8.375 seconds, which is about half the efficiency increase. Therefore, using dict instead of list is a good choice when multiple data members are needed for frequent lookups or visits.
