Akash  and  Vishal  are quite fond of travelling. They mostly travel by railways. They were travelling in a train one day and they got interested in the seating arrangement of their compartment. The compartment looked something like So they got interested to know the seat number facing them and the seat type facing them. The seats are denoted as follows : Window Seat :  WS Middle Seat :  MS Aisle Seat :  AS You will be given a seat number, find out the seat number facing you and the seat type, i.e.  WS ,  MS  or  AS . INPUT First line of input will consist of a single integer  T  denoting number of test-cases. Each test-case consists of a single integer  N  denoting the seat-number. OUTPUT For each test case, print the facing seat-number and the seat-type, separated by a single space in a new line. CONSTRAINTS 1<= T <=10 5 1<= N <=108 SAMPLE INPUT   2 18 40 SAMPLE OUTPUT...

https://www.geeksforgeeks.org/zoho-interview-set-1-campus/ Given a two dimensional array of string like <”luke”, “shaw”> <”wayne”, “rooney”> <”rooney”, “ronaldo”> <”shaw”, “rooney”> Where the first string is “child”, second string is “Father”. And given “ronaldo” we have to find his no of grandchildren Here “ronaldo” has 2 grandchildren. So our output should be 2.
