( 21769 ) A Equal or Not Equal PROGRAMMING constructive algorithms implementation

B"You had n positive integers a_1, a_2, ... , a_n arranged in a circle. For each pair of neighboring numbers ( a_1 and a_2 , a_2 and a_3 , ..., a_{n - 1} and a_n , and a_n and a_1 ), you wrote down: are the numbers in the pair equal or not. Unfortunately, you've lost a piece of paper with the array a . Moreover, you are afraid that even information about equality of neighboring elements may be inconsistent. So, you are wondering: is there any array a which is consistent with information you have about equality or non-equality of corresponding pairs? The first line contains a single integer t ( 1 <= t <= 1000 ) -- the number of test cases. Next t cases follow. The first and only line of each test case contains a non-empty string s consisting of characters E and/or N. The length of s is equal to the size of array n and 2 <= n <= 50 . For each i from 1 to n : For each test case, print YES if it's possible to choose array a that are consistent with information from s you know. Otherwise, print NO. It can be proved, that if there exists some array a , then there exists an array a of positive integers with values less or equal to 10^9 . In the first test case, you can choose, for example, a_1 = a_2 = a_3 = 5 . In the second test case, there is no array a , since, according to s_1 , a_1 is equal to a_2 , but, according to s_2 , a_2 is not equal to a_1 . In the third test case, you can, for example, choose array a = [20, 20, 4, 50, 50, 50, 20] . In the fourth test case, you can, for example, choose a = [1, 3, 3, 7] . "...
