Allocate Wells
Reported by candidates from Wells Fargo's online assessment. Pattern, common pitfall, and the honest play if you blank under the timer.
You've got an OA from Wells Fargo in your inbox, and the problem is called Allocate Wells. No problem text available yet, but candidates have reported this one since October 2024. The title hints at resource allocation or distribution logic, which almost always means greedy strategy or dynamic programming depending on the constraints. This is the kind of problem where the trick is spotting whether you're optimizing one dimension or balancing multiple. StealthCoder will catch the pattern live if you blank on the approach.
Pattern and pitfall
Allocation problems usually fall into two buckets: greedy assignment (pick the best option at each step) or DP optimization (find the globally optimal distribution). The Wells Fargo context suggests financial or account-level resource assignment. Without the full spec, assume the catch is either constraint-based (some wells or resources have limits), or you're minimizing waste or maximizing utilization. The common miss is treating it as a simple distribution when it actually requires you to respect hard boundaries or weights. If this is greedy, sort by priority and assign in order. If it's DP, build a table for possible allocations. StealthCoder's real value here is reading the exact constraint paragraph and immediately flagging whether sort-then-assign works or you need to explore subsets.
Drill it cold or hedge it with StealthCoder. Either way, don't walk into the OA hoping you remember the trick.

Allocate Wells FAQ
Is this a sorting-then-assign problem or do I need dynamic programming?+
Depends on the constraints. If you're just distributing a resource optimally with no interdependencies, greedy (sort and allocate) works. If allocations affect future options or you need to find the best subset, it's DP. Read the constraints carefully. Wells Fargo OAs usually test both, so expect constraints that rule out pure greedy.
What's the trap in allocation problems?+
Ignoring capacity or conflict constraints. You might optimize locally (assign to the highest-priority well) but violate a later constraint (total allocation exceeds available resource, or a well can't take more). Always validate end-state feasibility, not just greedy choices.
How do I prepare for this in 24 hours?+
Drill LeetCode problems on partitioning and greedy assignment (jump game, gas station, candy). Understand when to sort and when to use a heap or priority queue. For DP, review the knapsack variants. The insight for Wells Fargo problems is often 'sort by X, then validate constraints.'
Will this be multiple test cases or a single allocation?+
Wells Fargo OAs typically run a single scenario with multiple sub-tests (different input sizes, edge cases like zero resources or all-or-nothing constraints). Assume your solution needs to handle arrays up to 10k-100k elements and run in O(n log n) or better.
What if I blank during the OA?+
Start by writing a brute-force solution (iterate all possible allocations, pick the best). It'll be slow, but it's correct and buys time to think. Then optimize: if you see repeated subproblems, switch to DP. If greedy is working, add memoization as a safety net. StealthCoder will show you the pattern and sample solutions in real time if you're stuck.
