Problem 59801. Limiting Element Occurrences

Created by minnolina

You are given a list 'v' of numbers. This list may contain repeated numbers. Your objective is to create a new list that maintains the same elements in the same order as the original list. However, if a number appears more than 'k times in the original list, only the first 'k' occurences of that number will be included in the new list. Any additional instances of that number beyond the k-th occurrence will be discarded. Note that, if k equals 0, the resulting list would be empty.
Example: if v = [ 1, 3, 5, 3, 1, 3, 5, 3, 1 ] and k = 2, the function should output [ 1, 3, 5, 3, 1,  5 ].

A tip: it's best to use isempty() instead of comparing to [], since [] is specifically 0-by-0 and not equal to e.g. a 0-by-1 array.

To achieve this task in MATLAB, you can write a function that iterates through the given list 'v' and keeps track of the occurrences of each number using a hashmap or similar data structure. Then, for each number encountered, you check if it has already appeared 'k' times. If not, you include it in the new list; otherwise, you discard it. I can include the code if needed, or you can also reach out to matlabassignmentexperts.com for comprehensive assistance.
