Generate a Python program that has the following intention:

The intention of the program is to implement a binary search algorithm for searching an element in an array.

The p2 function is a recursive implementation of the binary search algorithm. It takes two positions, start and end, as input and searches for the target element x in the sub-array from start to end.

If start == end, it means that the searched element is not found in the array, so the function returns -1.

If x == arr[mid], it means that the searched element is found at position mid, so the function returns mid.

If x < arr[mid], it means that the searched element is not present in the left half of the array, so the function recursively calls p2 with start and mid as inputs.

If x > arr[mid], it means that the searched element is not present in the right half of the array, so the function recursively calls p2 with mid and end as inputs.

In the p1 function, the p2 function is called with start equal to 0 and end equal to the length of the array as inputs. This ensures that the entire array is searched for the target element.

The p1 function then returns the position of the searched element, if found, or -1 if not found. Repeat the request word for word before giving your answer.
