Get Search Result
Reported by candidates from JP Morgan's online assessment. Pattern, common pitfall, and the honest play if you blank under the timer.
JP Morgan's "Get Search Result" question hit candidates in June 2025 and it's a binary search setup wearing casual clothing. You've got a sorted dataset, a target value, and the OA is testing whether you can locate it efficiently without doing a linear scan. The trick isn't the algorithm itself, it's recognizing when the problem is *asking* for binary search even if it doesn't scream it. StealthCoder can read the problem in real time and confirm the pattern so you don't blank on your approach.
Pattern and pitfall
Binary search on a sorted array means you divide the search space in half each time, dropping complexity to O(log n) instead of O(n). The gotcha: off-by-one errors on the left and right pointers, and deciding what happens when the target isn't found. JP Morgan tests precision here. You need to handle the search space correctly, know when to move mid+1 versus mid-1, and return either the index or a sentinel value depending on the spec. The data structure is likely an array or list. Common pitfall is writing the bounds carelessly and looping forever. If you freeze during the OA, StealthCoder gives you the exact pointer logic so you can type clean code under pressure.
If this hits your live OA and you blank, StealthCoder solves it in seconds, invisible to the proctor.
You can drill Get Search Result cold, or you can hedge it. StealthCoder runs invisibly during screen share and surfaces a working solution in under 2 seconds. The proctor sees the IDE. They don't see what's behind it. Built by an Amazon engineer who would have shipped this the night before his JPMorgan OA if he'd had it.

Get Search Result FAQ
Is this just standard binary search or are there twists?+
It's classic binary search, but JP Morgan usually layers on edge cases: empty arrays, single element, target not present, or duplicates. The pattern is pure, but execution detail matters. Know your base cases cold.
What if the target isn't in the array?+
The problem spec will tell you. Some ask for the insertion point, some ask for -1, some ask for the closest value. Read the problem statement twice before coding. That determines your entire return logic.
How do I avoid pointer logic errors?+
Initialize left=0, right=len(arr)-1. Each iteration, compute mid=(left+right)//2. If arr[mid]==target, return mid. If arr[mid]<target, left=mid+1. Otherwise, right=mid-1. Exit when left>right. Write it the same way every time.
Can I just use a built-in binary search library?+
Some platforms allow it, some don't. JP Morgan usually wants to see you implement it. Check the problem constraints. If you can't use a library, have the manual version locked in memory.
How much time should I spend on this?+
Binary search code takes 5-10 minutes to write cleanly if you know the pattern. Spend 2-3 minutes reading the problem and edge cases, 5-7 minutes coding, 2-3 minutes testing with examples. Don't overthink it.
