Answer:
Running RECURSIVE-MATRIX-CHAIN is asymptotically more efficient than enumerating all the ways of parenthesizing the product and computing the number of multiplications of each.
the running time complexity of enumerating all the ways of parenthesizing the product is n*P(n) while in case of RECURSIVE-MATRIX-CHAIN, all the internal nodes are run on all the internal nodes of the tree and it will also create overhead.
Explanation:
Answer: A or B
Explanation: I think it's A or B Because they are the ones that make more sence
Answer:
The output of this code can be given as follows:
Output:
Here There Everywhere

and in the next line "But not" and "in Texas".
Answer:
var birthday = "12/2/1978";
Explanation:
It does not create a date object named birthday because in this statement the birthday is a string which contains 12/2/1978 a date it is not date object it is a string.All other three options are correct way to create a date object.
var birthday = new Date();
creates a date object with the current date and time.
we can also pass date string in the new Date().So var birthday = new Date("12/2/1978"); is also correct.
we can also pass year,month,day in new Date() In this order only.So option fourth is also correct.
Answer:
To store decimal values
Explanation:
Analyzing the given options.
(a)
Decimal values are digits and are to be treated as such. So, storing them as strings mean that they are no longer decimal values.
(b), (c) & (d)
List of colors, words and values that can't be used for calculations are all string values.
Take a for instance.
List of colors: "Red", "Yellow", "Blue",...
Words, "I", "am", "a", "boy"
Values that can't be used for calculations are non numerical data and as such, some of them could be strings.
Hence:
Option (a) answers the question
