Pull request overview

This pull request adds solutions for LeetCode problem No.0955 "Delete Columns to Make Sorted II" in multiple programming languages. The problem requires finding the minimum number of columns to delete from an array of equal-length strings to ensure the resulting strings are in lexicographical order.

  • Implements a greedy algorithm that processes columns from left to right
  • Tracks which adjacent string pairs have already established lexicographical ordering
  • Deletes a column only when it would violate the ordering for a pair that hasn't been settled
