Write a function that validates if a given string is a valid representation of an integer. The function should handle positive, negative, and zero values. It should also account for leading/trailing spaces, but return false if there are any non-numeric characters other than a single leading '+' or '-' sign. Details: The input is a string. The output is a boolean: true if the string represents a valid integer, false otherwise. A valid integer string can start with an optional '+' or '-' sign. The rest of the string must contain only digits. Leading and trailing whitespace should be ignored. The string must not contain any other non-numeric characters. Examples: +123 should return true -456 should return true 0 should return true +007 should return true abc should return false 12.3 should return false 1a should return false should return false ++12 should return false --12 should return false 12+ should return false 12- should return false Considerations: Handle empty strings gracefully. Be mindful of potential integer overflow issues (although the function does not need to explicitly check for it). Focus on validating the format of the string. Ensure your solution efficiently handles various edge cases and invalid inputs. Your function should demonstrate clear, concise, and well-documented code.

Tell me about a time you had to make a difficult decision with incomplete information. What was the situation? What information was missing? What decision did you make and how did you arrive at it? What was the outcome? What did you learn from the experience? For example, perhaps you had to decide whether to launch a new feature without complete user testing data, or whether to pursue a new market opportunity without a full understanding of the competitive landscape. Maybe you had to make a critical hiring decision without all the information you needed about the candidate's past performance. The key is to show that you can assess risks, weigh potential outcomes, and make sound judgments even when things are uncertain. Be sure to articulate the reasoning that led you to your decision, and reflect on the lessons you learned from the experience. This demonstrates your adaptability, problem-solving abilities, and your capacity for learning and growth.
