Python Coding: Primes and Counts

EasyPython

Problem

A GlobalLogic data-quality pipeline receives a batch of integers and a compact status string. Implement one Python function that identifies which integers are prime and counts how many times each character appears in the string.

Return a dictionary with two keys:

  1. prime_flags: a list of booleans aligned with the input integer array. A value is true only when the corresponding integer is prime.
  2. character_counts: a dictionary mapping each distinct character to its frequency. Preserve the order in which characters first appear.

Treat all integers less than 2 as non-prime. The input string contains lowercase English letters and is non-empty.

Formal Specification

  • Input: numbers, a list of integers, and text, a non-empty string.
  • Output: a dictionary with prime_flags: list[bool] and character_counts: dict[str, int].
  • A prime number is an integer greater than 1 with no positive divisors other than 1 and itself.

Constraints

  • 1 <= len(numbers) <= 10^4
  • -10^9 <= numbers[i] <= 10^9
  • 1 <= len(text) <= 10^5
  • text contains only lowercase English letters
