The bisect is based on the bisection method for finding the roots of functions.
This module comes with six functions divided into two categories.
These functions allow you to either find an index of an element or add a new element in the right position.

πFinding Elements with bisect
To find the index of an existing element in a sorted list, you want to bisect_left()
β οΈImportant: When using bisect to find an element, the method will return the element position or the element's expected position.

π Watch out for unsorted lists
Itβs your responsibility to sort the list before passing it to one of the functions.
If the elements arenβt sorted, then youβll most likely get incorrect results.
