Vaccine Distribution

PKJ
 Coding Problem Keys   Vaccine Distribution    Problem Statement  There is a large manufacturer of vaccine which produces M types of vaccines (whose formulas are derived from different pharma brands). The manufacturer needs to divide all the vaccines between N dealers. It is acceptable if some dealers do not get any vaccine. However, no dealer wants vaccine of different kinds which means that all vaccines that a dealer gets need to be of the same type. The manufacturer also knows that dealers will be jealous if a dealer gets too many vaccines. As an approximation, the jealousy level among the dealers is defined as the largest number of vaccines given to any dealer.  Task  Help the manufacturer to divide all the vaccines among the dealers such that the jealousy level is minimized.  Example  Assumptions N = 5 M = 2 arr = [7, 4]  Approach  There are 7 vaccines of 1st type and 4 vaccines of 2nd type. Let the two types be defined by...

String Rotation Odd and Even Positions

PKJ
 Coding Problem Keys   String Rotation Odd and Even Positions   Problem Statement  A string S and two integers M and N are passed as input. The program must rotate the characters present in the odd positions of the string M times and rotate characters present in the even positions of the string N times.  Boundary Condition(s)  2 <= Length of the string <= 1000. 1 <= M, N <= 1000.  Input Format  The first line contains the values of S, M and N separated by space(s).  Output Format  The first line contains the rotated string.  Example Input/Output 1   Input  technology 2 3  Output  logotycenh  Explanation  The characters present in the odd positions are 'tcnlg'. When rotated 2 positions, the value is 'lgtcn'. The characters present in the even position are 'ehooy', When rotated 3 positions, the value is 'ooyeh'. Hence the rotated string value is 'logotycenh'.  Example Input...

Function middle - CTS Pattern

PKJ
 Coding Problem Keys   CTS Pattern   Function middle   Problem Statement  You are required to correct the syntax of the given code without changing its logic. You can click on run anytime to check the compilation/execution status of the program. You can use printf to debug your code. The submitted code should be logically/syntactically correct and pass all test cases. Do not write the main() function as it is not required. Code Approach:  For this question, you will need to correct the given implementation. We do not expect you to modify the approach or incorporate any additional library methods. The function middle (int num) accepts an integer num as the input. If the count of the digits in the integer num is odd then the function returns the middle digit of the integer num. Else the function returns the two digits in the middle of the integer num. Another function findTenPowVal (int N) accepts a positive integer N as the input is available ...

Desktop Products

PKJ
 Coding Problem Keys   Desktop Products   Problem Statement  A company DigiComparts manufactures 52 types of unique products for laptop and desktop computers. It manufactures 10 types of laptop products and 42 types of desktop products. Each product manufactured by the company has a unique productID from a-z and and A-Z. The laptop products have productIDs (a, i, e, o, u, A, I, E, O, U) while the rest of the productIDs are assigned to the desktop products. The company manager wishes to find the sales data for the desktop products. Given a list of productIDs of the sales of the last N products, write an algorithm to help the manager find the productIDs of the desktop products.  Input Format  The first line of the input consists of an integer numOfProducts, representing the number of products to be considered in the sales data (N). The second line consists of N space-separated characters - productID 1 , productID 2 , ... , productID N  represen...

Highly Profitable Months

PKJ
 Coding Problem Keys   Highly Profitable Months   Problem Statement  The stocks of a company are being surveyed to analyse the net profit of the company over a period of several months. For an analysis parameter k, a group of k consecutive months is said to be highly profitable if the values of the stock prices are strictly increasing for those months. Given the stock prices of the company for n months and the analysis parameter k, find the number of highly profitable months  Example  Let the number of months be n = 8, the stock prices be stockPrices = [5, 3, 5, 7, 8] and the analysis parameter be k = 3. Following are the groups of k months in which the stock prices are strictly increasing: Hence the answer is 2.  Function Description  Complete the function countHighlyProfitableMonths in the editor below. countHighlyProfitableMonths has the following parameters:     int stockPrices[n]: the stock prices for n months.   ...
