Sometimes you need to limit array result to use. Such as you only need the value over 10 or, you need value under than 100. By use this algorithms, you can limit your array to specific value If array, Min, Max value was given, it returns array that contains values of given array which was larger than Min, and lower than Max. You need to give 'unlimit' to use only Min or Max. ex limit1,2,3,4,5, None, 3  1,2,3 Complexity  On tl:dr  array slicing by value
# tl:dr -- array slicing by value
def limit(arr, min_lim=None, max_lim=None):
    if len(arr) == 0:
        return arr

    if min_lim is None:
        min_lim = min(arr)
    if max_lim is None:
        max_lim = max(arr)

    return list(filter(lambda x: (min_lim <= x <= max_lim), arr))
