Answer:

Explanation:

The operator 'x++' is called the post increment operator, it is assign first and then increment.

The operator '++x' is called the pre increment operator, it is increment first and then increment.

So, both are increment operator which increment the value by one.

initially the value of x is zero,

++x increase the value to 1 and than assign to x.

then, x++ it assign to x first then increment by 1 means x=2

and so on.....

Their are five increment operator are used. so, the result is 5.

The following code should take a number as input, multiply it by 8, and print the result. In line 2 of the code below, the * sym

Juli2301 [7.4K]

Answer:

num = int(input("enter a number:"))

print(num * 8)

Explanation:

num is just a variable could be named anything you want.

if code was like this num = input("enter a number:")

and do a print(num * 8)

we get an error because whatever the user puts in input comes out a string.

we cast int() around our input() function to convert from string to integer.

therefore: num = int(input("enter a number:"))

will allow us to do print(num * 8)

4) Which is a more efficient way to determine the optimal number of multiplications in a matrix-chain multiplication problem: en

Assoli18 [71]

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.
