Answer:
Following is the expression written in "Bash script" (mixture of commands):
^\d{5}(?:[-\s]\d{4})?$
Explanation:
- ^ = For staring string (denotation).
- \d{5} = Matching 5 digits (first five unknown x's)
- (?:…) = Making Group (making group of former 5 digits)
- [-\s] = Match a hyphen or a space
(checking if a hyphen is present?)
- \d{4} = Matching 4 digits (next four unknown x's)
- …? = Pattern before it is optional
- $ = Ending of the string.(denotation)
Answer:
The answer is option A.
Explanation:
Negative numbers can be found by binary search, this makes option B incorrect.
Unsorted and randomized lists are also not things that support a binary search, options C and D are incorrect.
Binary search uses a technique where the middle element of the list is located and used to determine whether the search should be done within the lower indexed part of the list or the higher. So for a list to be binary search-able, it should be sorted and not randomized.
The answer is A.
I hope this helps.
Answer:
Following are the method to this question:
def __init__(self, _name, _breed):#defining Constructor
""" Constructor """
self.name = _name#assigning value in name variable
self.breed = _breed#assigning value in breed variable
self.tricks = []#defining tricks an empty list
Explanation:
In the above code, a parameterized constructor is defined, that hold two-variable "name and breed" in its parameter, and another object self is created for storing the value.
Inside the constructor two-variable, and one empty list variable "tricks" is defined that hold value in the name and breed variable, and the next step an empty list is defined, that store its value.
