AI Summary: This issue requests the addition of a C++ solution for the 'Find Minimum in Rotated Sorted Array' problem. The goal is to find the minimum element in a sorted array that has been rotated, with the constraint that the algorithm must run in O(log n) time. The problem description and examples are provided, along with constraints on the input array.

AI Summary: This GitHub issue proposes a C++ solution to merge two strings alternately. The approach uses two pointers to iterate through both strings, appending characters from each in turn until one string is exhausted. Any remaining characters from the longer string are then appended to the result. The solution aims for simplicity and efficiency, with a time complexity of O(n+m) and space complexity of O(1) excluding the output string.
