Paytm Coding Questions with Answers
Question 1 : Guess the word
Problem Statement :
Kochouseph Chittilappilly went to Dhruv Zplanet , a gaming space, with his friends and played a game called “Guess the Word”.
Rules of games are –
Computer displays some strings on the screen and the player should pick one string / word if this word matches with the random word that the computer picks then the player is declared as Winner.
Kochouseph Chittilappilly’s friends played the game and no one won the game. This is Kochouseph Chittilappilly’s turn to play and he decided to must win the game.
What he observed from his friend’s game is that the computer is picking up the string whose length is odd and also that should be maximum. Due to system failure computers sometimes cannot generate odd length words. In such cases you will lose the game anyways and it displays “better luck next time”. He needs your help. Check below cases for better understand
Sample input 0:
5 → number of strings
Hello Good morning Welcome you
Sample output 0:
morning
Explanation:
Hello → 5
Good → 4
Morning → 7
Welcome → 7
You → 3
First word that is picked by computer is morning
Sample input 1:
3
Go to hell
Sample output 1:
Better luck next time
Explanation:
Here no word with odd length so computer confuses and gives better luck next time

Question 2 : Share Holder (R -> Hard)
Problem statement :
Ratan is a crazy rich person. And he is blessed with luck, so he always made the best profit possible with the shares he bought. That means he bought a share at a low price and sold it at a high price to maximize his profit. Now you are an income tax officer and you need to calculate the profit he made with the given values of stock prices each day. You have to calculate only the maximum profit Ratan earned.
Note that:
Ratan never goes into loss.
Example 1 :
Price=[1,6,2]
Ratan buys it on the first day and sells it on the second.
Example 2 :
Price=[9,8,6]
The Price always went down, Ratan never bought it.
Input Format:
First line with an integer n, denoting the number days with the value of the stack
Next n days, telling the price of the stock on that very day.
Output Format:
Maximum profit done by Ratan in a single line.
Constraints:
Number of days <=10^8
Sample Input for Custom Testing
STDIN
———–

Sample Output
10
Explanation
The maximum profit possible is when Ratan buys it in 1 rupees and sells it in 11.

Question 3 : Stars Between Bars
Problem statement :
Given a string s consisting of stars “*” and bars “|” ,an array of starting indices starIndex,and an array of ending indices endIndex,determine the number of stars between any two bars within the substrings between the two indices inclusive . NOTE that in this problem indexing starts at 1.
- A Star is represented as an asterisk [*=ascii decimal 42]
- A Bar is represented as a Pipe [“|”=ascii decimal 124]
Example :
s=’|**|*|’
startIndex=[1,1]
endIndex=[5,6]
For the first pair of indices (1,5) the substrings is “|**|*” . There are 2 stars between a pair of bars
For the second pair of indices (1,6) the substring is “|**|*|” and there are 2+1=3 stars in between the bars.
Both of the answers are returned to the array [2,3].
Constraints :
int [n];each element[i] answers the query of startIndex[i] to endindex[i]
Constraints
1<=n<=105
1<=StartInde[i]<=endIndex[i]
Each Character of s is either “*” or “|”
>Input Format for Custom testing
First line contains a string S the next line contains an integer n , the no.of elements in startIndex. Each line i of the n subsequent lines contains an integer of startIndex.the next line contains an integer n , the no.of elements in endIndex. Each line i of the n subsequent lines contains an integer of endindex
>Sample Case 0
Sample Input for Custom Testing
*|*| → s=”*|*|”
1 → startindex[] size=1
1 → startindex= 1
1 → endindex[] size=1
3 → endindex=3
Sample output :
0
Explanation :
The substring from index =1 to index=3 is “*|*” . there is no consecutive pair of bars in this string.

Question 4 :Vampire Battle (R->Medium)
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.
