Problem Description
Given two string arrays word1 and word2, return true if the two arrays represent the same string, and false otherwise. A string is represented by an array if the array elements concatenated in order forms the string.
Key Insights
- Concatenation of strings in an array can be done using a simple loop or built-in functions.
- The problem can also be solved by directly comparing the concatenated results of both arrays.
- Efficiency in concatenation and comparison is crucial due to potential string lengths.
Space and Time Complexity
Time Complexity: O(n) where n is the total length of all strings in both arrays.
Space Complexity: O(1) if we disregard the output space for the concatenated strings.
Solution
To solve the problem, we can concatenate the elements of both arrays into single strings and then compare these two resulting strings. We can use a loop to iterate through each array or leverage built-in string concatenation functions to build the final strings. The solution will involve checking if both concatenated strings are equal to determine the final result.
