I have discussed the four easy problems of july’16 long challenge that I have solved fully. You are welcome to discuss about your approach on these problems.
My approach to question https://www.codechef.com/JULY16/problems/CHEFTET …
Since we have to use all the elements of array B so we can easily find “sum” of all the elements of array B and array A…
if(sum%n!=0) then ans is -1…
else we have to check if we can get the sum equal to sum/n…
Here’s the link to my approach https://www.codechef.com/viewsolution/10785468 …

I tested it around and worked perfectly fine but when I submit it there seems to be some mistake as it returns WA on all the tests.
@an2609 What do mean by ‘best submission’? Have you looked through all other submissions?
@tony_hager I meant in terms of running time. 0.00 sec
I didn’t go through your code, but I’m guessing that you’re not checking if the last element in ‘B’ has been used. I got WA in those tasks because of that.
@hemanth_1: I have checked the code and I’m using the last element of array B
hi, check this input.
1 3 4 8 9 11 15 21 30
output should be 10
your program gives 4.
check this input:
1 6 10 13 14
output should be 8 (one wire from coordinate 6 to coordinate 14)
your program gives 9.
