What is the meaning of O(M+N)?


Tag : performance , By : Pepe Araya

hop of those help? Yes, O(M+N) means the same thing as O(max(M, N)). That is different than O(min(M, N)). As @Dr_Asik says, O(M+N) is technically linear O(N) but when M and N have a meaning, it is nice to be able to say "linear in what?" Imagine the algorithm is linear in the number of rows and the number of columns. We can either define N = rows + cols and say O(N) or we can say O(M+N) where M is rows and N is columns.

Meaning of 'private' keyword in Alloy? Meaning of 'enum' declaration?

I wish did fix the issue. The Alloy 4 grammar allows signature declarations (and some other things) to carry a private keyword. It also allows Allow specifications to contain enumeration declarations of the form , This is my unofficial understanding of those two keywords.
enum nephews { hughie, louis, dewey }
open util/ordering[nephews] as nephewsOrd

abstract sig nephews {}

one sig hughie extends nephews {}
one sig louis extends nephews {}
one sig dewey extends nephews {}

fact {
  nephewsOrd/first = hughie
  nephewsOrd/next = hughie -> louis + louis -> dewey
}

should help you out Here's your original list myList sorted against your expected list of indices vs the two results you got:
Excepted:
>>> [myList[each] for each in [1, 0, 4, 2, 3]]
[1, 2, 6, 7, 3]
>>> [myList[each] for each in [1, 0, 3, 4, 2]]
[1, 2, 3, 6, 7]
myList = [2, 1, 7, 3, 6]

def get_rankings(list):
    return [sorted(list).index(each) for each in list]

print get_rankings(myList)
#[1, 0, 4, 2, 3]

Property has meaning INDEX_VALUE, but is not expected to have any meaning

To fix the issue you can do Within the schema, though it would only appear on the entire backup, there appeared a single element with wrong type. The wouldn't appear normally due to NDB's structure. The only way that I was able to fix this issue was to navigate the entities and remove the offending properties to ensure correctness.
It took a long time for the system to fix it via iteration, but they were not searchable items.

Can anyone tell me word by word meaning of Plain Old Java Object in java? also i mostly curious about 'Old' word meaning

To fix this issue "Old" has no real meaning in that sentence. In American English, a "plain old X" is just a "plain X," an X that isn't special. The "old" is just there for color, nothing more. (Nice link there from pvg.)
A Plain Old Java Object is a plain Java object, a Java object that isn't special. For more about what a POJO is, see Wikipedia's entry:
