For many fresh graduates who dream of working in cutting-edge tech, MathWorks is an incredibly attractive stage. So what does the MathWorks OA test? Read on.
2 Coding Questions vs. 50 MATLAB Multiple-Choice Questions
The MathWorks online assessment gives you two paths:
1. Solve two coding questions in any programming language.
2. Answer 50 MATLAB multiple-choice questions.
We recommend option 1: the coding path is more predictable and faster to prepare.
If you do need a ready-made bank of MATLAB multiple-choice questions, contact us for our curated collection.
Coding Question 1
Given a palindromic string of lowercase English letters `palindrome`, replace
exactly one character with any lowercase English letter so that the resulting
string is not a palindrome and is lexicographically smallest possible.
Return the resulting string, or an empty string if impossible.
Example:
Input: palindrome = "abccba"
Output: "aaccba"
Coding Question 2
Given two strings `s` and `t`, return the number of distinct subsequences
of `s` which equal `t`. Test cases guarantee the answer fits in a 32-bit signed integer.
Example:
Input: s = "rabbbit", t = "rabbit"
Output: 3
Explanation:
There are 3 ways to form "rabbit" from "rabbbit".
