cypher - Neo4j Optional match not working on 2.2.1 -


i have users data like

    id        username   ---------------------------     1         user1     2         user2     3         user3     4         user4     5         user5

there can friends relation between users. suppose user1 need list of user friends count , mutual frends count

in database

  • user2 have 2 friends user3, user4.
  • user4 friend of user3

i have tried this

match (me:user {is_deleted:false}) id(me)= 1 match (alluser:user {is_deleted:false}) optional match (alluser)<-[all_friends:friends]-(f:user {is_deleted:false}) optional match (me)-[mutual_friends:friends]->(f)  return id(alluser) user_id, alluser.username username, count(distinct(all_friends)), count(distinct(mutual_friends))

it provide me count of all_friend correct.

but not getting mutual_friends count return 0 if there realtions.

note:-this query works fine on neo4j 2.1 not working on neo4j 2.2.

what should in query make working.

please let me know if should explain more quetion.

thanks.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
