Jump Trading asked this one

Most of our problems come straight from real trading interviews. You solve it in a full editor, then run it against the actual test cases that decide the result.

Jump (trading) exactly a couple times.

MediumLanguage KnowledgeJump

You are given an integer array arr of size n and an integer k. You start at index 0 and perform exactly k moves. On each move you may either stay at your current index or advance to index i + 1 (if it exists). Before each move, you collect points equal to arr[i] where i is your current position.

Return the maximum total score achievable after exactly k moves.

Example 1

C++

arr = [1, 2, 3], k = 3 -> 6

// Collect at 0 (1), advance. Collect at 1 (2), advance. Collect at 2 (3).

// Total = 6.

Example 2

C++

arr = [1, 20, 3], k = 3 -> 41

// Collect at 0 (1), advance. Collect at 1 (20), stay. Collect at 1 (20).

// Total = 41.

Constraints

1 <= n <= 10^5
1 <= k <= 10^5
arr[i] are all integers (including negative)

1// C++23 using GCC 14.2

2// Debug with std::cerr

4long long max_score(const std::vector<int>& arr, const int k) {

Progress Tree

Most people prep by guessing what to study next. The Progress Tree takes that off your plate. It maps out every topic you need, tracks where you are, and points you to the next thing. You just follow it.

Get recruited. Pay nothing.

Active members get access to specialist quant recruiters who open doors and negotiate offers on your behalf. It costs you nothing. Skip the resume pile and get your foot in the door.

Train with someone who already got in

Your coach comes from top firms like Citadel, Jane Street, and Optiver. They sat for the same interview you're preparing for. Book a session and get the kind of feedback you can't find anywhere else.

Play modern quant interview games

We are building these from real Optiver-style interview challenges, so you are not playing random puzzles. They match what top firms test for today, and you will not find this full set on any other prep site.

Tenured instructors, not AI slop

Go deeper than question banks with courses on quant system design, behavioral interviews, and coding tutorials, all taught by real quants professionals with actual working experience. Learn the follow-ups, tradeoffs, and details no other prep site covers.

Follow Up 1: How do we handle repeated fields in your design?

struct MassQuoteEntry {  int Quantity;  double Price;}struct MassQuote {  uint32_t SecurityId;  std::vector<MassQuoteEntry> Entries;};

???

First 2 bytes tell us total message length, but how do we know how many bytes are left for the repeating group?

Bad Answer: Just take the total size and minus the fixed-length field sizes.

Bad because we can have multiple repeating groups.
