I find codeforces problems with rating 1900 easier than LC medium hard..

Does anyone else feel that leetcode medium hard problem or LC contest problem 3 is tougher than codeforces with problem rating 1700 or div2C, or only i feels it.

Here is the problem.

And here is one of the AC solution : http://codeforces.com/contest/999/submission/39534469 which is based on how to distribute M cards among N persons optimally such that joy is maximum. But how will we take care of this case : Suppose there are 3 players whose favourite card is say x and it occurs 5 times.

suppose p1 get 2 card , p2 = 2 , p3 = 1 and they want to have 4 cards in total.

Now how to select the remaining cards for them, since suppose if i give number y to player 1 it can be the favourite for some other player which will decrease his joy and may affect total joy.

when we do while(low < high )

suppose i get answer at mid =( low + high ) / 2 ;

if i again set low to mid , then there is a possibility that it will go in infinite loop .

for example :

low = 4 , high = 5 mid = 4

now suppose if mid is true and we again set low = mid , then low will be again 4 and it will go into infinite loop . what to do in that case , should we set low = mid + 1 .

how to decide when to set low = mid and when low = mid + 1 .

Given an array a[] = {1, 1 ,1 , -1} . you have to find all the subarrays of the given array whose sum is exactly = k.

example : a[] = { 1 , 1 , 1 , -1 } and k = 1

Ans = 4 all 3 one's + range from [2,4]

There is an geeks_article for it but the explanation is not good and clear and also without proof .

Can anyone explain me how to solve this problem with some explanation !

Thanks !
