Sample DuckDuckGo interview questions

1
Rotate a linked list to the right by k places. Given the head of a linked list, rotate the list to the right by k places. Input: head = [0,1,2], k = 4 Output: [2,0,1] Explanation: The list has a length of 3. Rotating by 4 is mathematically equivalent to rotating by 1 (4 mod 3 = 1).

2
Minimum Window Substring Find the minimum window substring that contains all characters of another string. Input: s = "a", t = "aa" Output: "" (Empty String) Explanation: The target requires two 'a's, but the source string only contains one, making it impossible to form a valid window.
codingmedium
3
Dot Product of Two Sparse Vectors Calculate the dot product of two sparse vectors. Input: nums1 = [0,1,0,0,2], nums2 = [0,0,0,0,5] Output: 10 Explanation: Multiplies the aligned non-zero values (2 * 5) and ignores all the zeros, yielding a dot product of 10.
codingmedium
4
Buildings with an Ocean View Find all buildings that have an ocean view. Input: heights = [1,2,3,4] Output: [3] Explanation: Since the ocean is to the right, only the rightmost tallest building (index 3) is not blocked by any others.
codingmedium
5
Encode and Decode Strings Encode a list of strings into a single string and decode it back. Input: strs = ["","hello",""] Output: ["","hello",""] Explanation: Prepends chunk lengths and a delimiter (e.g., "0#5#hello0#") to safely encode and perfectly restore empty strings.
