Question 03 : Device Name System

(Asked in OnCampus Drive August, 2023)

Problem statement: Rocky is a software engineer and he is creating his own operating system called “myFirst os”. myFirst os is a GUI (Graphical user interface) based operating system where everything is stored in files and folders. He is facing issues on creating unique folder names for the operating system . Help rocky to create the unique folder name for it’s os.If folder name already exists in the system and integer number is added at the name to make it unique. The integer added starts with 1 and is incremented by 1 for each new request of an existing folder name. Given a list of folder names , process all requests and return an array of corresponding folder names.

Example

n=5
foldername= [‘home’ , ‘myfirst’ ,’downloads’, ‘myfirst’, ‘myfirst’]
Foldername[0] = ‘home’ is unique.
Foldername[1] = ‘myfirst’ is unique.
foldername [2] =’downloads’ is unique.
Foldername[3] =’myfirst’ already exists in our system. So Add1 at the end of the folder name i.e foldername[3] =”myfirst1″
Foldername[4 ]=’myfirst’ also already exists in our system.So add 2 at the end of the folder name i.e. foldername[4]=”myfirst2″.

Function description

Complete the function folderNameSystem In the editor below
folderNameSystem has the following parameters
string foldername[n]: an array of folder name string in the order requested

Returns:

String[n]: an array of strings usernames in the order assigned

Constraints

1<=n<=10^4
1<=length of foldername[i]<20
foldername[i] contains only lowercase english letter in the range ascii[a-z]

Input Format:

The first line contains an integer n , denoting the size of the array usernames Each line i of the n subsequent lines (where i<=0<=n) contains a string usernames[i] representing a username request in the order received.

Sample case 0

4
home
download
first
first

Sample Output 0

home
download
first
first1

Explanation 0

foldername[0] = ‘home’ is unique
foldername[1]=’download’ is unique
foldername[2]= ‘first’ is unique
foldername[3]=’first’ is already existing . so add 1 to it and it become first1

Question 4: Amusement park

(Asked in OnCampus Drive July, 2023)

Problem Statement – Akshay loves to go to WONDERLA , an amusement park. They are offering students who can code well with some discount. Our task is to reduce the cost of the ticket as low as possible.

The cost of tickets can be removed by removing the digits from the price given. They will give some k turns to remove the digits from the price of the ticket. Your task is to help Akshay in coding a program that can help him to reduce the cost of a ticket by removing the digits from its price and getting the maximum possible discount.

Note – You cannot make the cost of a ticket zero. For eg -: If the cost of a ticket is 100, and you have 2 turns to reduce the price, the final price will be 1 and not zero.

Constraints:

1 <= number of tickets <= 10^5
1 <= K < Number of digits in Price of ticket

Input Format for Custom Testing:

The first line contains a string,Tickets, denoting the given cost of each ticket.
The next line contains an integer, K, denoting the number of tickets that is to be removed.

Question 6 :Vampire Battle (R->Medium)

(Asked in OnCampus Drive July, 2023)

Problem statement :

Stephan is a vampire. And he is fighting with his brother Damon. Vampires get energy from human bloods, so they need to feed on human blood, killing the human beings. Stephan is also less inhuman, so he will like to take less life in his hand. Now all the people’s blood has some power, which increases the powers of the Vampire. Stephan just needs to be more powerful than Damon, killing the least human possible. Tell the total power Steohan will have after drinking the bloods before the battle.
Note that: Damon is a beast, so no human being will be left after Damon drinks everyone’s blood. But Stephan always comes early in the town.

Input Format :
First line with the number of people in the town, n.
Second line with a string with n characters, denoting the one digit power in every blood.

Output Format :
Total minimum power Stephan will gather before the battle.

Constraints :
n<=10^4

Sample input :
6
093212

Sample output:
9

Explanation :
Stephan riches the town, drinks the blood with power 9. Now Damon cannot reach 9 by drinking all the other bloods.

Question 7: Array Subarray

(Asked in OnCampus Drive July, 2023)

Problem Statement: You are given an array, You have to choose a contiguous subarray of length ‘k’, and find the minimum of that segment, return the maximum of those minimums.

Sample input :

1 → Length of segment x =1
5 → size of space n = 5
1 → space = [ 1,2,3,1,2]
2
3
1
2

Sample output :

3

Explanation :

The subarrays of size x = 1 are [1],[2],[3],[1], and [2],Because each subarray only contains 1 element, each value is minimal with respect to the subarray it is in. The maximum of these values is 3. Therefore, the answer is 3

Question 10 :A Good Prime Number

(Asked in OnCampus Drive July, 2023)

Problem Statement :

A prime number is a number which is divisible by one and itself. Also a number is called a good prime number if the sum of its digits is a prime number. For example a number 23 is a good prime number because the sum of 2 and 3 ( 2+3=5) is 5 which is a prime number. You are given an integer K. Your task is to find the kth good prime number that is greater than a provided number N.

For example , 232 is a good prime number since the sum of all digits is 7 which is a prime number whereas 235 is not a good prime number.

Input format :

The first line contains an integer N.
The next line contains an integer K.

Output format :

A single integer which is a Kth good prime number that is greater than a provided number N.

Constraints :

1<=N<=10^5
1<=K<<=10^5

Sample Input 1:

4 4

Sample Output 1:

12

Explanation :

Good prime numbers starting from 4 are 5,7,11(1+1=2 which is prime number),12(1+2=3 which is prime number),14(1+4=5 which is a prime number) and so on. Because the sum of digits of an individual number is a prime number And 4 th good prime number is 12 in this series.Hence the output is 12.

Sample Input 2:

17 5

Sample Output 2:

29

Explanation :

Good prime numbers starting from 17 are 20,21,23,25,29…and the 5th prime number is 29.Hence the output is 29.
