Web8 Apr 2024 · Conclusion: In this blog, we discussed how to group anagrams in C++ using a hashmap. We sorted each string in the input list to use as the key for the hashmap and pushed the original string into the value vector of the corresponding key. After that, we looped through the hashmap and pushed the value vectors into a result vector to return. WebC++ Program Java Program Complexity Analysis for repeated substring pattern Example Input 1: str = “abcabcabc” Output: True Explanation: “abcabcabc” can be formed by repeatedly appending “abc” to an empty string. Input 2: str = “xyxy” Output: True Explanation: “xyxy” can be formed by repeatedly appending “xy” to an empty string.
