## Program 1: HOSTEL WARDEN

There is a hostel warden in some XYZ hostel. He is very strict with students. He has some set of rules to allow students to let them out. Students are in random order but warden don’t allow them in that way.
Rule 1- whose initial is a prime value should go out before whose initial is a composite value.
Rule 2- if two students have prime value , a student with less value goes out first
Rule 3- if two students have composite value , a student with greater value goes out first
NOTE:- consider the ASCII value of the initial to find it is prime or composite.

### Input Format

The first line of input contains the number of students N

• The second line of input contains random order of the students S.
(students at index zero goes out first and students at index N-1 goes last)

### Constraints

• 1<=number of students <=105
• 33<=ASCII Of Characters<=126

### Output Format

• The single line of output should contain the required modified order of students to go out.

### Test Cases

#### Case 1

• Input

## Program 2: Jagannath and his Brothers

Jagannath was with two of his young brothers in work. He wants to work less, and wants his brothers to work more, as he is a lazy person. Now, in the work field, there is an array of buildings, from where they can earn money. So that there arises no conflict between his brothers that who earns more, he arrives in one building, tells his brother that the very building will bring the most money (Which may not be true), and tells one of his brothers to go to the left and another one to go to the right.

You have to write a program so that you can predict which building will be getting Jagannath, and how much money each of his friends are gonna earn.

### Input Format

• First line saying the number of test cases, n.
• Then next n pairs of lines, first one depicting the number of buildings k and second one containing k space separated integers denoting the number of earnings possible.

### Constraints

• 1 <= n <= 10 ^ 6
• 1 <= k  < n
• -10 ^ 9 <= a[i] <= 10 ^ 9 (Earnings)
• 1 <= t <= 25

### Output Format

• n lines, with the index of building jagannath working, space separately the money His brothers each making. If the combination is not possible, answers are 0.

### Test Cases

#### Case 1

• Input

Shushil has gone crazy after he lost a big amount of his money in the share market. Now he keeps all the money he has distributed in his room and calculates them in a very problematic way. Every time he calculates hisnetworth, he writes it down adding  with the last 3 rooms he has one.

Then after that when he reaches the next room he adds the last 3 rooms’s money with the money found in that room and adds again. Suppose he is in ith room, he will add i-1,i-2 and i-3th rooms money with ith one and add it into his net worth (if the rooms exist).

Given an array of money in the rooms, find what will he calculate as his net worth?

### Input Format

• First line saying the number of rooms, r
• Next line r space separated money amounts in each room

## Question 7: Strange rule

Problem Statement – There are two friends Ram and Shyam. They saw each other after a very long time. Then they remember the rule they make when they are of very small age. They have decided that whenever they see each other they will move towards each other in a very dramatic way.

• Let’s say Ram and Shyam are ‘D’ meters apart.
• Ram moves 1 meter in each step he takes but Shyam moves are increases linearly starting from 1, i.e., he moves 1 meter in his first step then 2 meters on the second, 3 meters on the third step and so on till he cannot take a step.
• Assume they both take steps simultaneously till shyam is able to make a step. Whenever shyam can’t make a step, he waits patiently at that place and the rest of the distance is covered by Ram.
• Calculate the minimum number of steps they take in total before meeting each other.
• Your task is to output the minimum number of total steps required before Ram and Shyam can meet each other.

Input Format:

• The first line contains the number of test cases ‘T’.
• The next ‘T’ line contains the distance ‘D’.

Constraints:

• 1 T 105
• 1 D 105

Output Format:

• Output ‘T’ lines with each line containing a single integer denoting the minimum number of jumps they take before hugging each other for each test case.

Sample Input

1

3

Sample Output

3

Explanation

• Let Ram be at position 0 of x-axis and Shyam be at position 3 of the x-axis.
• Ram jumps to position 1 and simultaneously Shyam jumps to position 2.
• Now Shyam can’t make a jump because if he does so, then he will be jumping over Ram which is undesirable. So she patiently waits at position 2.
• Finally, Ram jumps to position 2 and they hug each other
• You can clearly see 3 jumps are required. Two by Ram and One by Shyam.
• So the output is 3.

## Question 9: Encryption is EVERYTHING!

Problem Statement – Vaibhav is head of regiment 22 and he used to send some information to the Ashish who is head of 33rd regiment. The problem here is there are enemies nearby regiments. So Vaibhav has security issues now. He decides to encrypt the information and then transfer to Ashish.

But Vaibhav has no knowledge on encryption. Help Vaibhav to encrypt the data.He is instructing you to encrypt as follows

• if the ascii value of “z” is 3(assumption) so it will be replaced by “c”.
• if ascii value of “a” is 3(assumption) so it will be replaced by “d”

Input Format

• A string of alphabets(all alphabets are in lowercase ie. a to z).

Constraints:

• 1<=lenght_of_string<=10^5
• All lowercase alphabets

Output Format :

• A string following the above mentioned encryption rule ( All alphabets must be in lowercase a to z).

Explanation

1+2=3

3-3=0

0*4=0

`s=list(input())op="+-*/"ans=""flag=0for i in s:    if i in op:        flag=1        a=i      elif i not in op and flag==1:        ans=str(eval(ans+a+i))         elif(i not in op):         ans+=i            flag=0      print(ans) `
`import java.util.Scanner;public class Application27{  public static void main (String[]args)  {    Scanner sc = new Scanner (System.in);    String s = sc.nextLine ().trim ();    String ans = "";    int flag = 0;    char a = '1';    for (int i = 0; i < s.length (); i++)      {	char ch = s.charAt (i);	if (ch == '+' || ch == '-' || ch == '*' || ch == '/')	  {	    flag = 1;	    a = ch;	  }	else if (ch != '+' && ch != '-' && ch != '*' && ch != '/'		 && flag == 1)	  {	    if (a == '+')	      {		int temp = Integer.parseInt (ans) + (ch - '0');		ans = String.valueOf (temp);	      }	    if (a == '-')	      {		int temp = Integer.parseInt (ans) - (ch - '0');		ans = String.valueOf (temp);	      }	    if (a == '*')	      {		int temp = Integer.parseInt (ans) * (ch - '0');		ans = String.valueOf (temp);	      }	    if (a == '/')	      {		int temp = Integer.parseInt (ans) / (ch - '0');		ans = String.valueOf (temp);	      }	  }	else if (ch != '+' && ch != '-' && ch != '*' && ch != '/')	  {	    ans += ch;	    flag = 0;	  }      }    System.out.println (ans);  }}`

## Question 12: Love test

Problem Statement – A couple(both are professors in Mathematics)  got a doubt about who loves their partner more. So they decided to play a maths game to decide who loves more. They will take some numbers and the one who makes that number to 1 will win. They can only reduce numbers by following some rules. Check if the number is a power of 2. If it is a power of 2, the person divides the number by 2 Else, the person subtracts the number by the highest power of 2 lower than the number. Then the person gives the newly obtained number to their partner.

Sorry I didn’t tell you the names of the couple, they are  Steve and Carter.

Always Steve starts the game.

Input format

• First line contains an integer T denoting the number of games.
• Each of the next T lines contain an integer N, the starting number for the game.
• 0<T<11
• 0<N<2^64

Note: Since N can be a very large number, use appropriate data types for the variables.

Output format

• For each of the T games, print the person name who loves more on a new line.

Note: The output format should be followed strictly.

Sample Input

2

6

3

Sample Output

Carter

Steve

Explanation

Game 1:

Steve starts, 6 is not a power of 2. Hence, Steve subtracts 6 by the highest power of 2 smaller than 6, which is 4:  6-4 = 2

Carter receives 2. 2 is a power of 2. Hence, Player B divides 2 by 2 to get 1.

Since Carter reduced the number to 1, Carter is the winner.

Game 2:

Steve starts. 3 is not a power of 2. Hence, Player A subtracts 3 by highest power of 2 smaller than 3, which is 2:  3-2 = 1

Hence, Steve wins.

Sample Input

3

10

12

13

Sample Output

Steve

Carter
