QUESTION
I got below question in one of my company entrance exam. All testcases were passing except 4 testcase. Can someone try to lookout what can be the possible scenario, which might be failing. Question and solutions are given below:
Mean, Median and Mode
Given 'n' integers find their mean median and mode. You are requested to fill in a function that takes an input integer 'input1' (1<=input1<=1000) and an integer array input2[] containing 'input1' integers and returns output1 as the mean output2 as the median and output3 as the mode.
The mean and median must be correct to six decimal places.
Mean: Defined as the avearge of all numbers in array.
Median : Define as the middle element of array.
If n is even the median is the average of the two middle elements If n is odd, the median is the middle element of array.
Note : For finding the median,elements in the array have to be listed in numerical order from smallest to largest.
Mode: Defined as the number in the array with highest frequency. If many numbers have the same highest frequency then the mode is calculated by breaking the ties in favour of the smallest of the numbers.
Input specifications :
Input1 : Integer in the range of 1<=input1<=1000 denoting length of input array.
Input2 : Integer input array.
Output specifications :
Return output1(double) variable as the mean.
Return output2(double) variable as the median.
Return output3(int) variable as the mode.
Sample Test Case 1:
input1: 3
input2: {1,2,3}
Output : 2.000000,2.000000,1
Sample Test Case 2:
input1: 5
input2: {41, 18467, 6334, 26500, 19169 }
...Output : 14102.200000,18467.000000,41
ANSWER
Answered 2021-Mar-20 at 17:06The issue is in findMode. You don't handle the case where there are multiple numbers with the same highest frequency. The problem statement says:
If many numbers have the same highest frequency then the mode is calculated by breaking the ties in favour of the smallest of the numbers.
The simplest solution is to store the mode value only when it is lower than the previous mode value - initializing the mode value to the highest possible value.

QUESTION
I am automatically adding a coupon for specific products which works fine, however this prevents me from being able to remove the coupon and I can't add a different one. I get an AJAX response back saying the coupon was added or removed but it doesn't actually do anything.
If I comment this code out, the adding/removing of coupons works fine.
I am trying to remove the coupon via AJAX, is there anything to lookout for that might prevent this from functioning correctly? It looks like as soon as a coupon is added it removes it again.
Which I believe is due to the below code

I am working on a screen scraper to pull football statistics down from www.pro-football-reference.com. I'm currently scraping from the main player's stat page and then diving into their individual page with their statistics by year.
I was able to implement this process successfully with my first set of players (quarterbacks, using the Passing Table). However, when I attempted to re-create the process to get running back data, I am reciving an additional column in my data frame with the values "Unnamed: x_level_0". This is my first experience with HTML data so I'm not sure what piece I missed, I just assumed it would be the same code as the quarterbacks.
Below is the QB Code sample and the correct dataframe:
