The correct answer is many-to-one

This kind of relationship is likely to happen when two tables share the same primary key because one entity had values that are related to another one that has distinctive values. It is usually applied by primary key relationships and the relationships normally are between fact and dimension tables and levels in hierarchy as well.

Write a program to take in a time-of-day on the command-line as 3 integers representing hours, minutes, and seconds, along with
nexus9112 [7]

Answer:

In Python:

hh = int(input("Hour: ")) * 3600

mm = int(input("Minutes: ")) * 60

ss = int(input("Seconds: "))

seconds = int(input("Additional Seconds: "))

time = hh+ mm + ss + seconds

hh =  int(time/3600)

time = time - hh * 3600

mm = int(time/60)

ss = time - mm * 60

while(hh>24):

   hh = hh - 24

print(str(hh)+" : "+str(mm)+" : "+str(ss))

Explanation:

We start by getting the time of the day. This is done using the next three lines

<em>hh = int(input("Hour: ")) * 3600</em>

<em>mm = int(input("Minutes: ")) * 60</em>

<em>ss = int(input("Seconds: ")) </em>

Then, we get the additional seconds

<em>seconds = int(input("Additional Seconds: "))</em>

The new time is then calculated (in seconds)

<em>time = hh+ mm + ss + seconds</em>

This line extracts the hours from the calculated time (in seconds)

hh =  int(time/3600)

time = time - hh * 3600

This line extracts the minutes from the calculated time (in seconds)

mm = int(time/60)

This line gets the remaining seconds

ss = time - mm * 60

The following iteration ensures that the hour is less than 24

while(hh>24):

   hh = hh - 24

This prints the calculated time

print(str(hh)+" : "+str(mm)+" : "+str(ss))
