Least Stressful Path
Reported by candidates from Salesforce's online assessment. Pattern, common pitfall, and the honest play if you blank under the timer.
Salesforce asked this in July 2024, and it's a graph traversal problem disguised as a path-optimization question. You're hunting for a route through a weighted graph where the goal isn't shortest distance but lowest stress, usually measured by maximum edge weight on the path. The OA doesn't tell you the graph structure upfront, so you'll need to parse it fast. StealthCoder reads the problem statement and feeds you the approach before you lock in a solution.
Pattern and pitfall
This is a min-max path problem, not a shortest-path one. Dijkstra won't work directly because you're minimizing the worst edge, not the sum. The pattern: binary search on the answer (what's the minimum stress level needed?) combined with graph traversal, or use a priority queue ordered by maximum stress seen so far instead of cumulative distance. Common trap: coding Dijkstra reflexively and then realizing your edge weights matter differently. The trick is recognizing that you're bottleneck-optimizing, not summing costs. StealthCoder as a safety net means if you freeze on whether to use Dijkstra or BFS with a different comparator, you get the real approach in real time without breaking flow.

Least Stressful Path FAQ
Is this really asking for the path with the smallest maximum edge?+
Yes. 'Least stressful' means you want to minimize the worst stress point on any single edge. It's not about total stress. That's why naive shortest-path fails. You're looking for the path where the heaviest edge is as light as possible.
Can I solve this with Dijkstra?+
Not the standard version. You can modify it: instead of tracking cumulative distance, track the maximum edge weight seen so far. Use a min-heap ordered by that maximum, not the sum. It's Dijkstra-adjacent but a different comparator.
What if the graph is dense or has cycles?+
Cycles don't break you because you're exploring paths, not finding the absolute minimum globally. A modified Dijkstra or BFS with proper visited tracking handles it. The key is the priority queue ordering, not the graph shape.
How do I parse the input quickly on the OA?+
Look for adjacency list or matrix format. Build a graph structure (dict of lists or 2D array). Identify source and destination. Then pick your algorithm. Don't overthink the parsing. The tricky part is the algorithm, not the setup.
Is this still asked after mid-2024?+
Graph traversal with a twist stays common at Salesforce. The specific flavor changes, but min-max or bottleneck path problems appear regularly. Knowing this pattern is a hedge worth having.
