Create a code to find the median of an array of integers. The input array will contain n elements, where n is a positive integer not exceeding 10^6. The output should be the median value of the array.
Constraints:
- The input array should not be modified.
- The time complexity of your solution should not exceed O(nlog... | codefeedback | [

I have this problem : Non-decreasing Array with Specific Conditions
Description are as below: Given an array `nums` with `n` integers, your task is to check if it could become non-decreasing by modifying at most one element. However, the modification should not change the parity of the number (i.e., if the number is ev... | codefeedback | [

Write a function to find the n-th Fibonacci number for a given n, using a recursive approach. The function should handle negative values of n and return an error message if the input is invalid.
However, the function should have a time complexity of O(n) and space complexity of O(1). In other words, the function shoul... | codefeedback | [
