u made a wrong assumption, try this tc:
1
1
10
0
4
F 0 9
E 0 9
I 0 9
S 0 4
answer for the query should be 5
Many many thanks for this tc. Now i have the bug. i made wrong when flipping. for example when flipping the left child — i used : if(Left.p==0) Left.p=1; if(Left.p==1) Left.p=0; if(Left.p==2) Left.p=-1; if(Left.p==-1) Left.p=2;
But it should be: if(Left.p==0) Left.p=1; else if(Left.p==1) Left.p=0; else if(Left.p==2) Left.p=-1; else if(Left.p==-1) Left.p=2;
& now it's Accepted.. Thanks again.. :)
