## zig-zag arrangement in Array

Consider an array a= (1 4 3 -1 10 6) of length N, so zig-zag arrangement of elements is arr < arr  > arr < arr > arr < . . . . arr[n-2] < arr[n-1] > arr[n] Here, first we need to run code which will sort the data in descending order .For this you can refer to this blog.
