Prolifics Coding Questions with Solutions

Question 1 : Bank Compare Problem

Problem Description

Question – : There are two banks – Bank A and Bank B. Their interest rates vary. You have received offers from both banks in terms of the annual rate of interest, tenure, and variations of the rate of interest over the entire tenure.You have to choose the offer which costs you least interest and reject the other. Do the computation and make a wise choice.

The loan repayment happens at a monthly frequency and Equated Monthly Installment (EMI) is calculated using the formula given below :

EMI = loanAmount * monthlyInterestRate / ( 1 – 1 / (1 + monthlyInterestRate)^(numberOfYears * 12))

Constraints:

1 <= P <= 1000000
1 <=T <= 50
1<= N1 <= 30
1<= N2 <= 30

Input Format:

First line: P principal (Loan Amount)
Second line: T Total Tenure (in years).
Third Line: N1 is the number of slabs of interest rates for a given period by Bank A. First slab starts from the first year and the second slab starts from the end of the first slab and so on.
Next N1 line will contain the interest rate and their period.
After N1 lines we will receive N2 viz. the number of slabs offered by the second bank.
Next N2 lines are the number of slabs of interest rates for a given period by Bank B. The first slab starts from the first year and the second slab starts from the end of the first slab and so on.
The period and rate will be delimited by single white space.

Output Format: Your decision either Bank A or Bank B.

Question 2 : Minimum Number of Clicks

Problem Statement – Sahil watches TV all day and gets bored. He started playing this dumb game of identifying minimum number of inputs needed to reach a channel. As his cousin, you have to help him, but you live far from his house. So you decide to write a code that will ask Sahil for some inputs and give outputs respectively.

Here are the problems you need to keep in mind,

There are 13 buttons on his remote: 10 buttons for the numbers (0-9) to form integers denoting respective channel index, “Up channel” button and “ Down channel” button for going i +1th channel and i-1th channel from i respectively, and a “Last viewed” button to see what’s the last channel before it.
The number buttons allow you to jump directly to a specific channel (Ex: to go to channel 172 by typing 1,7,2).
If the channel which you are in is ith and that is the max channel index possible, by Up channel, you will reach the first channel possible. Same goes for the down channel button. You can go to the highest channel possible if you go down from the lowest channel possible.

Sahil can get from one channel to the next in one of the two ways.

Sahil’s parents have set some parental control on some channels on Aniruth’s television. The “Up Channel “ and “Down buttons” buttons skip these channels as these channels are not viewable.

Given a list of channels to view, the lowest channel, the highest channel, and a list of blocked channels, your program should return the minimum number of clicks necessary to get through all the shows that Anirudh would like to match.

Input Format

First line is the lowest Channel
Second-line is the highest Channel
Followed by a number of blocked channels B,
and the next B lines contain the actual blocked channels.
Followed by the number of Channels to view V, and the next V lines contain the actual channels to view.

Constraints

The lowest channel on the television will be greater than 0. and less than or equal to 10,000.
The highest channel on the television will be greater than or equal to the lowest channel. and less than or equal to 10.000.
The list of channels that are blocked on Anirudh’s television. All the channels in this list will be valid channels (greater than or equal to lowest channel, less than or equal 1 to highest channel). Duplicates may be Ignored. The blocked list can be a maximum of 40 channels.
The sequence that Sahil must view contains between 1 and 50 elements. inclusive. All channels in this sequence are not in the blocked list and are between lowest channel and highest channel. Inclusive.

Question 3 : Treasure Hunt

Rohan and his team are participating in the Treasure Hunt event of college in which in each step they have to solve one problem to get a clue of Treasure location . Rohan’s team has performed very well and reached the final step where they have to provide a code of a problem to get a final clue about treasure .

Given a string s, they need to find the longest palindromic subsequence’s length in s.
A subsequence is a sequence that can be derived from another sequence by deleting some or no elements without changing the order of the remaining elements.

The string contains only lowercase letters.

Write a program to help Rohan’s team that takes in input as String x and returns the length of the longest palindromic subsequence of x.

Input Specification:
input1: string input

Output Specification:
Return the length of the longest palindromic subsequence

Example 1:
Input: s = “bbbab”
Output: 4
Explanation: One possible longest palindromic subsequence is “bbbb”.

Example 2:
Input: s = “cbbd”
Output: 2
Explanation: One possible longest palindromic subsequence is “bb”.

Question 4 : Coin Distribution Problem

Problem Statement

Find the minimum number of coins required to form any value between 1 to N,both inclusive.Cumulative value of coins should not exceed N. Coin denominations are 1 Rupee, 2 Rupee and 5 Rupee.Let’s Understand the problem using the following example. Consider the value of N is 13, then the minimum number of coins required to formulate any value between 1 and 13, is 6. One 5 Rupee, three 2 Rupee and two 1 Rupee coins are required to realize any value between 1 and 13. Hence this is the answer.However, if one takes two 5 Rupee coins, one 2 rupee coin and two 1 rupee coin, then too all values between 1 and 13 are achieved. But since the cumulative value of all coins equals 14, i.e., exceeds 13, this is not the answer.

Input Format:
- A single integer value.

Output Format:
- Four space separated integer values.
  - 1st – Total number of coins.
  - 2nd – number of 5 Rupee coins.
  - 3rd – number of 2 Rupee coins.
  - 4th – number of 1 Rupee coins.

Constraints:
- 0 < n < 1000

Refer the sample output for formatting

Sample Input

Sample Output

6 1 3 2

Explanation

The minimum number of coins required is 6 with in it:
- minimum number of 5 Rupee coins = 1
- minimum number of 2 Rupee coins = 3
- minimum number of 1 Rupee coins = 2

Using these coins, we can form any value with in the given value and itself, like below:

Here the given value is 13

For 1 = one 1 Rupee coin
For 2 = one 2 Rupee coin
For 3 = one 1 Rupee coin and one 2 Rupee coins
For 4 = two 2 Rupee coins
For 5 = one 5 Rupee coin
For 6 = one 5 Rupee and one 1 Rupee coins
For 7 = one 5 Rupee and one 2 Rupee coins
For 8 = one 5 Rupee, one 2 Rupee and one 1 Rupee coins
For 9 = one 5 Rupee and two 2 Rupee coins
For 10 = one 5 Rupee, two 2 Rupee and one 1 Rupee coins
For 11 = one 5 Rupee, two 2 Rupee and two 1 Rupee coins
For 12 = one 5 Rupee, three 2 Rupee and one 1 Rupee coins
For 13 = one 5 Rupee, three 2 Rupee and two 1 Rupee coins

Question 5 : Permutations

Williamson is an analyst he needs to analyse a particular topic for performing analysis for that he needs to find a permutation of a given object.He don’t know how to find permutation so for simplifying his work he is hiring one software developer who can code for him and find a permutation and combination of a given object.

Consider you are giving an interview to williamson for working with him. Find a permutation of given input to proof that you are fit for his requirement.

Input Specification:
nCr where n and r are numbers given by Williamson to you
nCr is defined as n! / (r! x (n-r)!)

Here, n! denotes the factorial of a number. Also, you have to calculate this number as modulo
Input Specification:

input1: The number n.
Input2: The number r.
Input3: The number m,
.

Output specification:

The value of nCr%m.

Example 1:
Input1: 3
Input2: 2
Input3: 10000000009

Output:3

Explanation:
n=3.r=2,m=100 So, n!=3!=6, r!=2!=2, (n-1)!= 1!=1.
So, nCr = (6/(2*1))%1000000009= 3.

Example 2:
input1: 5
input2: 2
input3: 1000000009

Output: 10

Explanation:
n=5,r=2, m=100 So, n!=5!=120, r!=2=2, (n-1)!= 3!=6.
So, nCr = (120/(2*6))%1000000009= 10.
