3. Longest Substring Without Repeating Characters
Find the length of the longest substring with all unique characters — GoDaddy applies this sliding-window pattern when validating domain labels and parsing URL path segments where repeated characters signal malformed input.
- #49mediumfoundational
49. Group Anagrams
Cluster strings that are anagrams of each other — GoDaddy uses the same sorted-key hash-table pattern to group similar domain name variations and detect typo-squatting slugs in their marketplace.
- #56mediumfoundational
56. Merge Intervals
Merge all overlapping intervals into the minimum non-overlapping set — GoDaddy's SRE team applies this pattern to consolidate maintenance windows and detect scheduling conflicts across their global hosting infrastructure.
- #139mediumfoundational
139. Word Break
Determine whether a string can be segmented into dictionary words — GoDaddy's domain-suggestion engine applies this DP pattern to split brandable strings like 'websitebuilder' into human-readable word sequences for new TLD recommendations.
- #146mediumfoundational
146. LRU Cache
Design a data structure that evicts the least-recently-used entry when capacity is hit — this is the canonical DNS resolver cache problem that GoDaddy's infrastructure team asks to assess whether you can build O(1) get and put using a doubly-linked list plus a hash map.
- #200mediumfoundational
200. Number of Islands
Count connected land masses in a binary grid using BFS or DFS — GoDaddy's network team models hosting-cluster topology as a grid and uses this pattern to identify isolated server groups during infrastructure partitioning reviews.
- #208mediumfoundational
208. Implement Trie (Prefix Tree)
Build a trie that supports insert, search, and prefix lookup — GoDaddy's domain-search autocomplete is a direct application of this structure, making prefix-tree questions a staple in their platform-engineering interviews.
- #547mediumfoundational
547. Number of Provinces
Count connected components in an adjacency-matrix graph — GoDaddy maps this to identifying isolated hosting-cluster groups where servers are directly or transitively connected through shared VPC peering relationships.
