<ul data-eligibleForWebStory="true"><li>Hashing is a key tool in solving string problems efficiently in Data Structures and Algorithms (DSA).</li><li>A simple hash array or map, like int hash[256] = {0}, is often sufficient for handling character frequency or pattern-matching tasks in DSA.</li><li>When approaching a string problem, consider whether it can be transformed into a frequency or pattern-matching problem for which hashing is a valuable technique.</li><li>Mastering character hashing is essential for excelling in coding interviews and enhancing DSA problem-solving skills, making it a fundamental pattern rather than a mere trick.</li></ul>
