Implement Two-Pointer Algorithms

converging pointers on sorted input

Challenge 2 of Arrays & StringsBeginner~50 minFree

Master the two-pointer technique on arrays and strings. Across five steps you will build converging-pointer search, palindrome checking, in-place reversal, in-place deduplication, and the classic container-with-most-water problem.
