Your code is seems to right for long input but some of
long long input(In VC __int64) it may be wrong i think.
As:
Input:9223372036854775808
Output:63
But your result is:0
So try with it in VC by using __int64.
Hope it will be help.

Do u think it is correct? for (i = 1; i <= n; i ++) { if (left[i] == right[n+1-i] && left[i] > mx) mx = left[i]; } I think no. It should be like mx=0; for(i=1;i<=n;i++) { if((left[i]<=right[i]) && (left[i]>mx))mx=left[i]; if((left[i]>=right[i]) && (right[i]>mx))mx=right[i]; } Why it should ,i think ...

10594 - Data Flow

I verify again and again but may be sample I/O for one is wrong:
input:
4 4
1 3 3
3 4 4
1 2 2
2 4 5
20 100
output:
140
I think it should be

3 4 4
1 2 2
2 4 5
20 10
output:
140
Am i correct or incorrect?

You don't need critical judge data cause you can create it. by using random function in following equation: (x+y)*y=p; (labs(x-y))*x=q; You can create two file in where one is for x y and another is for p q Now make second file is your problem's(10512) input and first file is judge output.Find diffe...
