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 Source Code in C: #include<stdio.h...

Magical Word ! Hacker Earth

Dhananjay has recently learned about  ASCII  values.He is very fond of experimenting. With his knowledge of  ASCII  values and character he has developed a special word and named it Dhananjay's Magical word. A word which consist of alphabets whose  ASCII  values is a prime number is an Dhananjay's Magical word. An alphabet is Dhananjay's Magical alphabet if its  ASCII  value is prime. Dhananjay's nature is to boast about the things he know or have learnt about. So just to defame his friends he gives few string to his friends and ask them to convert it to Dhananjay's Magical word. None of his friends would like to get insulted. Help them to convert the given strings to Dhananjay's Magical Word. Rules for converting: 1.Each character should be replaced by the nearest Dhananjay's Magical alphabet. 2.If the character is equidistant with 2 Magical alphabets. The one with lower  ASCII  value will be considered as its replacement. ...
