Searching a sorted list? [closed]

Answer 1

Python:

def find_elem_in_sorted_list(elem, sorted_list):
    # https://docs.python.org/3/library/bisect.html
    'Locate the leftmost value exactly equal to x'
    i = bisect_left(sorted_list, elem)
    if i != len(sorted_list) and sorted_list[i] == elem:
        return i
    return -1
