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 …

hi you have post very informative question. for best c programming training institute please visit the following link.c programming training

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.

can anyone tell me for which test case i am getting wrong for all.i have tested all the test case but ts failing for all my soln

hi, check this input.

9

101010101

1 3 4 8 9 11 15 21 30

output should be 10

your program gives 4.

Can someone help me figure out why my solution isn’t being accepted, I’ve tried alot of test cases. https://www.codechef.com/viewsolution/10829172.

check this input:

5

10001

1 6 10 13 14

output should be 8 (one wire from coordinate 6 to coordinate 14)

your program gives 9.

Can someone please post the approach to solve CHEF and ELECTRICITY?

Can you help me find the problem with my code for Chef and Electricity: https://www.codechef.com/viewsolution/10810212 .

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.
