Maximum Coins Heroes Can Collect
A medium-tier problem at 68% community acceptance, tagged with Array, Two Pointers, Binary Search. Reported in interviews at Deutsche Bank and 0 others.
Maximum Coins Heroes Can Collect doesn't show up everywhere, but Deutsche Bank has asked it. It's a medium-difficulty problem that looks straightforward until you realize the greedy approach fails and the actual solution demands a deeper algorithmic trick. Most candidates miss the pattern on first sight, which is exactly why you're reading this now. The problem sits at a 68% acceptance rate, meaning one in three people who attempt it blank or time out. If this problem hits your live assessment and you freeze on the approach, StealthCoder surfaces a working solution in seconds, invisible to the proctor.
Companies that ask "Maximum Coins Heroes Can Collect"
Maximum Coins Heroes Can Collect is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Made by an Amazon engineer who watched the leaked-problem repo become an industry secret. He decided you should have it too.
Get StealthCoderThe trap here is thinking you can just sort and pick the biggest coins greedily. The real constraint involves coordination between multiple actors or positions, which breaks naive selection. You'll likely need to model the problem as a state-space search or optimization problem where two pointers or binary search narrows down the solution space. The topics tell the story: sorting gets you organized, prefix sums let you compute range totals fast, and binary search or two pointers eliminates impossible states. The acceptance rate proves this isn't a pattern most people see in their drill sessions. When you hit this live and your first instinct doesn't work, you don't have time to rebuild your logic mid-OA. StealthCoder is the hedge for that moment, running invisibly and giving you the working approach so you can implement with confidence.

Maximum Coins Heroes Can Collect interview FAQ
Is this problem really only asked by Deutsche Bank?+
The data shows Deutsche Bank in the reports. It's a niche problem, which means it's less drilled in typical prep courses. That's why seeing it live is dangerous. You can't assume it'll appear at your target company, but you also can't assume you'll have time to invent the solution if it does.
Why is the acceptance rate only 68% if it's medium difficulty?+
Medium problems with high acceptance rates usually have a clear greedy or straightforward DP path. At 68%, candidates are hitting a hidden constraint or optimization requirement that kills the obvious approach. The pattern isn't obvious from the problem statement alone.
Do I need binary search to solve this, or is it optional?+
Binary search appears in the topic list, suggesting it's either the core approach or a critical optimization. You likely won't solve it efficiently without it. Prefix sum also appears, hinting that range queries are central to the logic.
What's the difference between this and a standard coin-collection greedy problem?+
Standard greedy problems let you pick independently. This one clearly involves multi-actor dynamics or constrained positions, forcing you to model state and search or optimize. The two pointers and sorting topics confirm you're managing position or order in a non-trivial way.
How much time should I spend on this in a real assessment?+
If you see the pattern within 10 minutes, keep going. If you're still guessing at 15 minutes, you've hit the wall this problem is built to test. At that point, a working solution from StealthCoder keeps you moving instead of burning 45 minutes on a wrong approach.
