1. Problem Statement:
Tomorrowland is a futuristic cityscape somewhere in time and space. A teenage girl with scientific curiosity Casey Newton
and a former genius inventor Frank, set out for a dangerous mission to unearth the secrets of Tomorrowland.In the course of 
their mission, they identified the decoded form of earth language in the sign boards and at all other places at Tomorrowland.
Frank examined the decoded text and interpreted its rules.
The decoded text contains only lower case alphabets.One alphabet in earth language is equal to the floored average of 2 
alphabets in Tomorrowland.
For eg: "acde" in Tomorrowland is "bd" in earth

Write a C program to help Frank and Casey that inputs a string which refers to the decoded word in Tomorrowland 
and converts it to the equivalent earth language word.

Input format:
	The only line of input is a string that corresponds to the decoded word in tomorrowland.
Output format:
	The output is a string that corresponds to the equivalent earth language word.
	Refer to sample input and output for formatting specifications.
	Sample Input 1:
	acde
	Sample Output 1:
        bd
	Sample Input 2:
	acdf
	Sample Output 2:
	be
	
Problem Statement 2:
2.Frank  explained to Casey that Tomorrowland has n dimensions unlike Earth which has only 3 dimensions. 
  Being an unexplored place, Frank also felt that there is a need for them to know the distance between any points in
 the "n" dimensional space. Write a program that will input the value of  "n" the number of dimensions and the 
 two vectors in an n-D space and would compute the distance between them.
Input Format: 
The first input is an integer n, corresponds to  number of dimensions. 
The next n elements corresponds to the starting coordinates . 
The next n elements corresponds to the ending coordinates .
Output Format: 
Output consists of a float value which corresponds to the distance between the two dimensions . 
Display the distance correct to 2 decimal places.
Sample Input and Output: 
[All text in bold corresponds to input and the rest corresponds to output]
Enter the number of dimensions in tomorrowland
2
Enter the starting co-ordinates
10
15
Enter the ending co-ordinates
20
25
Distance between them is 14.14  
Problem Statement -3
3.Athena, an AA (Audio-Animatronic) robot sneaks a "T" pin into Casey's belongings with the intention that Casey's 
  help would save the world.Casey sees the pin in her belongings and discovers that upon contact,the pin instantly shows 
  her a view of Tomorrowland. She briefly explores  the vision until the pin's battery runs out. Given current battery %, 
and rate of discharge of the battery(% per sec), find the no. of minutes  and seconds for which she can see the Tomorrowland.
Input format:
	The first input is a float value which corresponds to the battery life remaining
	The second input is a float value which corresponds to the rate of battery discharge.
Output format:
  Refer the sample output:
	Current battery percentage
	80
	Rate of discharge per second
	1
	Time remaining 1.33 minutes               

	Sample Input and Output:

	[All text in bold corresponds to input and the rest corresponds to output]
4.	Hugo and Ursula
Casey's sees the "T" pin in her belongings  and assisted by her brother Nate, finds and visits a Houston memorabilia store
related to the pin. The store's owners are two Audio-Animatronic (AA) robots, Hugo and Ursula. They question Casey 
where she got the pin and approach to attack Casey and Nate despite the girl knew nothing about the pin. Casey and Nate
are in a square shaped room that has nxn unit square tiles, where n is the length of the room. 
They are currently standing in one of the corners and the exit door is present diagonally opposite to the corner 
where they are standing.
If they manage to escape from the room, they are safe. Since Hugo and Ursula are robots, they are programmed to 
travel only in four directions (top, left, down and right) placing themselves in the center of each tile they are moving.
Given the length of the room and the speed  in which the robots move, find the minimum speed in which Casey and 
Nate need to run in order to escape from the robots. Casey and Nate can very well run straight on the diagonal.
	Input Format: 
	The first line of the input is an integer that corresponds to the length of the room in metres.  
	The second line of the input is a float value that corresponds to the Speed of Audio-Animatronic (AA) robots 
	in meter per second.	 
	Output Format: 
	Output is a float value that corresponds to the minimum speed of humans in meter per second .  
	Sample Input and Output:
	[All text in bold corresponds to input and the rest corresponds to output.]
	Length of the room in meters
	25
	Speed of Audio-Animatronic (AA) robots in meter/sec
	3
	Humans need to run at a minimum speed of 1.50 m/s
