This is an assignment I must complete in CSP and I'm completely dumbfounded as to how to do it:
"Get two numbers from the user. The first will be the number to count up to, the second will be the number to count by.
For example, the user gives the numbers "20" and "3"
1
4
7
10
13
16
19
Note: it didn't actually reach 20."
Seems pretty standard
for i = start, finish, increment do
print(i)
end
Is a for loop, so just substitute finish and increment with the numbers and set start to 1

I want to write where condition in a SQL Server query which has following conditions:

payment mode='cash' and sataus not equal to completed
How I can write these 4 condition b
We put the sets of conditions in brackets. In the following either all the conditions in the first parenthesis must be met or all those in the second.
Where
(paymentmode='Bank'
and Status <> 'Paid')
Or
(paymentmode='cash'
and status <> 'completed')

simulate 1 million tests of three fair coin flips
tests = np.random.randint(2, size=(int(1e6), 3))
sums of all tests
test_sums = tests.sum(axis=1)
proportion of tests that produced exactly one head
(test_sums == 2).mean()
if heads is represented by 0 then any test containing only one heads will contain one 0 and two 1, thus their sum will be exactly 2
more descriptive way of writing the code would be to check every occurrences of head
heads = tests == 0
then sum the occurrences per test
heads_per_test = heads.sum(axis= 1)
and see where total occurrences are exactly 1
(heads_per_test == 1).mean()

Want to filter dataset with SQL query using RegEx to filter entries based on the time (hour) e.g. 19:XX or 09:XX. The hour part of the string would be in position 12 and 13.
Checked a few other questions and articles, but I'm very new to this and can't figure it out. Don't know which SQL database it is, but I work with it on Google BigQuery.Thanks for your help!
Screenshot of data entries
The standard way to access the hour in a date/time is:
where extract(hour from timecol) = 19
Not all databases support extract. All should have something similar.

Could anyone help me on the below please?

Sorted Brad.
Used Case/When logic. Here's the Answer:
Case
WHEN W1.Plex = 'Duplex' then (F1.images / 2)
Else F1.images
