Video Summary :
Approach 1: This method uses the Sieve of Eratosthenes to precompute prime numbers up to the given range. It then extracts primes within the given bounds and finds the closest prime pair by iterating through the list.
Approach 2: This approach checks each number in the range individually for primality. It maintains a list of found primes and returns early if two consecutive primes are found with a minimal gap; otherwise, it finds the closest pair at the end.
