The space complexity depends on the specific algorithm used. The algorithms presented in this article have the following space complexities: Method 1 in C and Python: O(n), where n is the total number of elements in both arrays (due to the merged array). Method 2 in C: O(1) (constant space) because it does not require an additional merged array.

Method 1 and 2 in C++: O(n), where n is the total number of elements in both arrays (due to the merged vector). Also Read: Java Program to Determine the Color of a Chess Square Method 1 and 2 in Java: O(n), where n is the total number of elements in both arrays (due to the merged priority queues). It's important to note that the space complexity does not include the space required to store the input arrays or the output median.
