Use sliding window with hashmap tracking frequencies; expand right pointer, shrink when distinct elements exceed K, update maximum subarray sum continuously during traversal. 1. Longest Increasing Subsequence (LIS) Use dynamic programming or binary search with a tails array; iterate through elements, update positions using lower_bound, achieving O(n log n) time complexity for efficient subsequence length calculation. 2. Detect Cycle in Directed Graph Use DFS with recursion stack or Kahn’s algorithm; track visited and path nodes, if revisited in recursion stack, cycle exists, otherwise graph remains acyclic during traversal.

They ask dsa from dp and graph which is difficult I couldn't complete the question. Good work culture very much to learn . Don't know about slaray I have applied for ml
