Debug Frequent Mobile Crashes | Dataford Interview Questions

How would you approach debugging a mobile application that crashes frequently?

For this coding exercise, analyze Android crash stack traces by counting identical traces, filtering by a minimum occurrence threshold, and ranking the remaining traces. Implement analyze_crashes(crash_events, min_occurrences), where the input is a list of stack-trace strings and the output is a list of dictionaries containing stack_trace and count, sorted by descending count and then alphabetically by trace.

Constraints include up to 10^4 traces, a positive threshold, and non-empty trace strings.

Constraints

0 <= len(crash_events) <= 10^4
1 <= min_occurrences <= 10^4
Each stack trace is a non-empty string
Results are sorted by descending count, then ascending stack trace

Function Signature

def analyze_crashes(crash_events, min_occurrences):
