C++
Write a ternarySearch function. A ternary search is similar to a binary search, but it divides an array into three sections instead of two - find the two points that divide the array into three (almost) equal sections, and then use these points to decide where to search for the key.
#### Part 1
Write a Python function (`binary_search`) that implements the binary search algorithm.
This function will take a list argument (`values`), a value to search for (`to_find`), a start index (`start_index`), and an end index (`end_index`). The function will return `True` if `to_find` is present in `values`, and `False` otherwise.
Below, you will find some code to test your binary search:
```python
values = [2,4,6,8,10,12,14,16,18,20]
print(binary_search(values, 14, 0, len(values) - 1))
print(binary_search(values, 7, 0, len(values) - 1))
```
The output of the test code is below:
```
True
False
```
#### Part 2
Modify your `binary_search` function to count the number of comparisons (==, <, <=, >, or >=). The function will now return both the number of comparisons made and the `True` or `False` result.
The code below calls your function, and creates a simple ASCII bar chart of the number of comparisons (divided by 10, to account for small differences).

- Modify the recursive Fibonacci function to employ the memoization technique discussed in this chapter. The function creates a dictionary and then defines a nested recursive helper function named memoizedFib. You will need to create a dictionary to cache the sum of the fib function. The base case of the fib function is the same as before. However, before making any recursive calls, the helper function looks up the value for the function’s current argument in the dictionary (use the method get, with None as the default value). If the value exists, the function returns it and skips any recursive calls. Otherwise, after the helper function adds the results of its two recursive calls, it saves the sum in the dictionary with the current argument of the function as the key. Note: The program should output in the following format: n fib(n) 2 1 4 3 8 21 16 987 32 2178309 ---------------------------------------------------------------------------------- def…arrow_forwardCode in C.

- An array with an odd number of elements is said to be balanced if all elements (except the middle one) are strictly greater than the value of the middle element. Note that only arrays with an odd number of elements have a middle element. Write a C++ function that accepts an integer array and returns 1 or “Balanced” if it is a balanced array, otherwise it returns 0 or “Not Balanced”.arrow_forwardC++ (a) Use iteration (b) Use recursion (c) Convert the function that you wrote in part (b) into a template function.

Write a function that takes a vector of integers, an integer n representing the number of elements in that vector, and an integer b. Implement the sequential search algorithm to look for the integer b in the vector. The sequential search works as follows: you must look at all the elements of the vector until you find the b, from the first to the last. The function must return an integer representing how many elements the function tested until it found b. If it does not find the function, it must return 0.
