String Character Occurrence and Missing Number

GSPANN QA automation utilities need a compact validation routine for text payloads and a nearly complete numeric sequence. Implement one function that performs both analyses in a single call.

1. Count every character in text, preserving case and treating spaces and punctuation as characters.
2. Given values, containing the integers from 1 through 50 with exactly one value missing and exactly one other value duplicated, return the missing and duplicated values without sorting the input.

Formal Specification

Implement analyze_input(text, values).

• Input: text is a string. values is a list of exactly 50 integers.
• Output: Return a dictionary with two keys:
  • counts: a dictionary mapping each distinct character to its frequency, in the order characters first appear.
  • missing: the absent integer.
  • duplicate: the integer that occurs twice.

The input is valid, and the character count must be case-sensitive. Use linear time and avoid modifying values.
