Some Coding Questions for Practice
Question 1
Wipro’s client eBay wants to run a campaign on their website, which will have the following parameters, eBay wants that on certain x products, they want to calculate the final price, for each product on eBay there will be a stock unit parameter, this parameter will denote, how many items are their in their fulfillment center
Now, while these numbers if are positive means product x is available in the fulfillment center and if not than the product is not available and cannot be shipped to the customer
Now the price on for each product varies based on the distance of the customer from the fulfillment center. Now, each product is in different fulfillment zone. Now, these values are 00’s kms for each centurion km. The price available would further increase by factor distance.
You’ve to find the maximum discount price for each product if the product can be shipped.
Following are the input/output parameters :
Input
- The first line of the input will contain number of products.
- The second line will contain price for each of these products.
- The third line contains shipping distance in 00’s kms
- The fourth line contains SKU’s
Output
- It will contain the final price for each deliverable item in SKU’s
Example :
Input:
- 6
- 87 103 229 41 8 86
- 3 1 9 2 1 2
- 7 -21 30 0 -4 -3
Output
- 261 2061

Question : 5
(asked in Wipro On Campus, MIET Meerut, Aug, 2019)
Problem Statement
You are required to implement the following function:
Int SumNumberDivisible(int m, int n);
The function accepts 2 positive integer ‘m’ and ‘n’ as its arguments.
You are required to calculate the sum of numbers divisible both by 3 and 5, between ‘m’ and ‘n’ both inclusive and return the same.
Note
0 < m <= n
Example
Input:
m : 12
n : 50
Output 90
Explanation:
The numbers divisible by both 3 and 5, between 12 and 50 both inclusive are
{15, 30, 45} and their sum is 90.
Sample Input
m : 100
n : 160
Sample Output
510
