Python Binary Search

Write an efficient binary search function in Python that returns the index of a target value or -1 if not found

def binary_search(arr: list[int], target: int) -> int:
    left, right = 0, len(arr) - 1
    while left <= right:
        mid = left + (right - left) // 2
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            left = mid + 1
        else:
            right = mid - 1
    return -1

# Example usage:
# sorted_list = [1, 3, 5, 7, 9, 11, 13]
# print(binary_search(sorted_list, 7))  # Output: 3
React Custom Hook

Create a React custom hook called useDebounce that debounces a value by a given delay

import { useState, useEffect } from 'react';

function useDebounce<T>(value: T, delay: number): T {
  const [debouncedValue, setDebouncedValue] = useState<T>(value);

  useEffect(() => {
    const timer = setTimeout(() => {
      setDebouncedValue(value);
    }, delay);

    return () => {
      clearTimeout(timer);
    };
  }, [value, delay]);

  return debouncedValue;
}

export default useDebounce;

// Usage:
// const debouncedSearch = useDebounce(searchTerm, 300);
