                OR              

The cost of travelling by Luxury Bux is Rs.X and the cost of travelling by Share Auto is Rs.Y.

 

She plans to spend minimal amount for travel.

Given X and Y, help her to decide whether to travel by luxury bus or by share auto.

 

Input and Output Format:

Input consist of 2 integers – X and Y. Assume that X is never equal to Y. Refer sample input and output for formatting specification.

 

[All text in bold corresponds to input and the rest corresponds to output]

Sample Input and Output 1:

Enter the cost of travel by luxury bus

40

Enter the cost of travel by share auto

35

Minimal cost travel is by auto

 PROBLEM -16:

                                               LAB SEATING ARRANGEMENT

 There are 2 programming labs, each with a seating capacity of 90. There are 240 students with registration numbers from 1 to 240. All 240 students cannot be accomodated in the labs at the same time. It has been decided to conduct theory classes for 60 students every week. It has been planned to conduct theory classes for all students with registration numbers being a multiple of 4. Students with registration numbers from 1 to 120 with registration numbers not a multiple of 4 need to be seated in Programming Lab I and students with registration numbers from 121 to 240 with registration numbers not a multiple of 4 need to be seated in Programming Lab II.

Given the registration number of a student, write a  program to specify the lab or hall in which the student needs to be seated.

 

Input Format:

Input consists of 1 integer which corresponds to the registration number of the student.

 

Output Format:

Output consists of the string “Lab 1” or “Lab 2” or “Theory Session”.

Refer sample input and output for further formatting specifications.
