Question
What is the precise purpose of merge() method in Merge Sort?
a. It inserts maximum element from the subarray to the end
b. It rearranges all elements according to the pivot point
c. It sorts an array using Divide and Conquer concept
d. It joins two unsorted subarrays into one
e. It joins two sorted subarrays into one
Solution
The precise purpose of the merge() method in Merge Sort is:
e. It joins two sorted subarrays into one.
This is the key step in the Merge Sort algorithm where the sorting actually happens. The merge() function takes two sorted subarrays and merges them into a single sorted array. This is done in a way that the resulting array is also sorted. This process is repeated recursively until we have a single sorted array.
