Search Suggestions System | Type, Jump, Take 3 | LeetCode 75 #71

LeetCode 1268 Search Suggestions System — the autocomplete problem, explained for beginners in Hindi. We sort the products once, then for every typed letter we binary-search (lower_bound) the first match and take up to 3 lexicographically smallest suggestions. Every C++ line explained with its WHY — what breaks if the line is removed. Then the trie version: walk one edge per keystroke, collect 3 words with an a-to-z DFS, and the honest answer to when the trie actually beats sort plus binary search (streaming queries). Full animated dry run on products = ["mobile","mouse","moneypot","monitor","mousepad"], searchWord = "mouse", plus the "tatiana" total-miss case, the bags vs baggage lexicographic surprise, correctness proof, complexity analysis, and edge cases.
