Word Break II | Backtracking

Short summary

Word Break II tutorial covering the backtracking algorithm through recursion trees, Java implementation, and complexity analysis. Shows both basic recursive approach (exponential time) and memoization optimization, with related LeetCode problem references.

• •Backtracking algorithm generates all valid word partitions from string using dictionary
• •Includes recursion tree diagrams, Java code, and O(1) HashSet lookup optimization
• •Demonstrates pruning invalid paths and memoization to convert exponential to DP
