Sieve of Sundaram
The Sieve of Sundaram is a deterministic algorithm for finding all prime numbers up to a specified integer. It works by eliminating numbers of the form i + j + 2ij where i and j are integers, leaving only the primes (except 2). It is less commonly used than the Sieve of Eratosthenes but offers a different mathematical approach to prime generation.
Developers should learn the Sieve of Sundaram when studying number theory, algorithm design, or mathematical computing, as it provides an alternative method for prime sieving with educational value. It is useful in academic contexts, competitive programming (e.g., for prime-related problems), or when implementing custom prime algorithms for performance comparisons, though it is generally slower than the Sieve of Eratosthenes for practical applications.
