Someone claims that the big O notation does not make sense at all, and they give the following example. An algorithm A that proc

esses an input set of N elements takes time, in seconds, given by T(N) = 10000*N + 0.00001*N^3. They say that the large constant (10000) associated with the N will always dominate over the small constant (0.00001) associated with the N^3. You say that this algorithm A is:_____

Answer:

Big Oh notation is used to asymptotically bound the growth of running time above and below the constant factor.

Big Oh notation is used to describe time complexity, execution time of an algorithm.

Big Oh describes the worst case to describe time complexity.

For the equation; T(N) = 10000*N + 0.00001*N^3.

To calculate first of all discard all th constants.

And therefore; worst case is the O(N^3).

Assume that month is an int variable whose value is 1 or 2 or 3 or 5 ... or 11 or 12. Write an expression whose value is "jan" o
Tamiku [17]

Answer:

The code is given below

Explanation:

The correct syntax would be to place appropriate parenthesis.

(month==1?"jan":(month==2?"feb":(month==3?"mar":(month==4?"apr":(month==5?"may":(month==6?"jun":(month==7?"jul":(month==8?"aug":(month==9?"sep":(month==10?"oct":(month==11?"nov":"dec")))))))))));

Similarly, you can also use the following code:

String[] months = { "jan", "feb", "mar", "apr", "may", "jun", "jul", "aug", "sep", "oct", "nov", "dec" };

int month = 1;

String monthDescription = months[month - 1];

An expression containing the operator && is true either or both of its operands are true. True/False
Luba_88 [7]

Damm [24]

Answer:

I am doing it with python.

Explanation:

nums = '9 -8 -7 -6 -5 -4 -2 0 1 5 9 6 7 4'

myfile = open('data.txt', 'w')

myfile.write(nums)

myfile.close()

myfile = open('data.txt', 'r')

num1 = (myfile.read())

num1 = num1.split()

print(num1)

print(type(num1))

for x in num1:

   x = int(x)

   if x < 0:

       minus = open('dataminus.txt', 'a')

       minus.write(str(x) + ' ')

       minus.close()

   elif x>= 0:

       plus = open('dataplus.txt', 'a')

       plus.write(str(x)+' ')

       plus.close()
