__________________ 💻 Merge_sort💻 ______________ Definition Merge_sort :- Merge sort runs in  0(n log n) time it is a very efficient sorting algorithm with near optimal number of comparison it is best described using a recursive  algorithm.  " Merge_sort " follows ' divide and  conquer  ' approach.  The algorithm process in 3 steps :- * if a contains 0 or 1 elements than it is already     sorted otherwise, divide a into two sub - array       number of  equal number elements  .  * combine the sub - arrays to from a single final       sorted array maintaining the ordering of array  * conquer means sort the two sub - arrays   recursive using the merge_sort.   Merge_ sort Images :-           *This images are assigning order : ⬇️              *Descending order Merge_sort :- ⬇️     Syntax :-   ...
