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...

Roy and Profile picture

Roy wants to change his profile picture on Facebook. Now Facebook has some restriction over the dimension of picture that we can upload. Minimum dimension of the picture can be  L x L , where  L  is the length of the side of square. Now Roy has  N  photos of various dimensions. Dimension of a photo is denoted as  W x H where  W  - width of the photo and  H  - Height of the photo When any photo is uploaded following events may occur: [1] If any of the width or height is less than L, user is prompted to upload another one. Print " UPLOAD ANOTHER " in this case. [2] If width and height, both are large enough and (a) if the photo is already square then it is accepted. Print " ACCEPTED " in this case. (b) else user is prompted to crop it. Print " CROP IT " in this case. (quotes are only for clarification) Given L, N, W and H as input, print appropriate text as output. Input: First line contains  L . Second ...
