You are given the arrival and departure times of N trains at a railway station in a day. You need to find the minimum of platforms required for the railway station such that no train waits i.e No train should wait for the platform to be clear or free.

You are given a string S of words. Your task is to find the number of palindrome words in the given string S. A word is called palindrome, if it reads the same backwards as forwards.

Words are separated by one or more whitespace characters.

Ninja has an array ‘A’ of size ‘N’. He recently created a topic ‘Complete Sum’ and defined the term ‘completeSum[i]’ = Sum ( A[0] … A[i] ).

Output the complete sum array of array ‘A’.

Example :

N = 3
A = [ 1, 2, 3 ] 

Explanation : 

Complete sum for index 0 is ‘A[0]=1’.

Complete sum for index 1 is ‘A[0] + A[1]’ = 3.

Complete sum for index 2 is ‘A[0] + A[1] + A[2]’ = 6.

So, we output [ 1, 3, 6 ].
