Ternary Search Algorithm in D Programming Language

The given code is an implementation of ternary search algorithm in D programming language.

The ternary search algorithm is a searching algorithm that divides the search space into three parts and determines which part the target element lies in. It is similar to binary search but divides the array into three parts instead of two.

In this code, the 'ternarySearch' function takes an array 'arr' and a target element 'target' as input and returns the index of the target element in the array. If the target element is not found in the array, it returns -1.

The 'main' function reads the number of elements 'n' and the target element 'target' from the user. It then creates an array 'arr' of size 'n' and reads the elements of the array from the user. It then calls the 'ternarySearch' function to find the index of the target element in the array. If the index is not -1, it prints the index + 1 (since array indices start from 0 in D programming language). Otherwise, it prints -1. Finally, it deletes the array 'arr' and returns 0.

Overall, the code efficiently implements the ternary search algorithm to search for a target element in an array.
