Answer:

An Oracle sequence uses the identity column property to automatically number rows.

Explanation:

An Oracle sequence is a tool that can be used to generate a number sequence. Oracle has the capacity to help you create an auto-number field by using one of its tools called sequence.

A sequence is an object in Oracle that is used to generate a number sequence for input to a table. This is required when you need to generate primary key values by the use of identity columns.

So, Oracle sequence can automatically number rows by the use of identity columns.

A series circuit and identify how voltage is split up by each load in the circuit?
Vlada [557]

The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. ... The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor. If the circuit is broken at any point, no current will flow.

Write a program that prompts the user to enter a series of numbers between 0 and 10 asintegers. The user will enter all numbers
Anna71 [15]

Answer:

The program in Python is as follows:

import collections

from collections import Counter

from itertools import groupby

import statistics

str_input = input("Enter a series of numbers separated by space: ")

num_input = str_input.split(" ")

numList = []

for num in num_input:

         if(num.lstrip('-').isdigit()):

                   if num[0] == "-" or int(num)>10:

                             print(num," is out of bound - rejecting")

                   else:

                             print(num," is valid - accepting")

                             numList.append(int(num))

         else:

                   print(num," is not a number")

print("Largest number: ",max(numList))

print("Smallest number: ",min(numList))

print("Range: ",(max(numList) - min(numList)))

print("Mode: ",end = " ")

freqs = groupby(Counter(numList).most_common(), lambda x:x[1])

print([val for val,count in next(freqs)[1]])

count_freq = {}

count_freq = collections.Counter(numList)

for item in count_freq:

         print(item, end = " ")

         lent= int(count_freq[item])

         for i in range(lent):

                   print("#",end=" ")

print()

See attachment for program source file where comments are used as explanation. (Lines that begin with # are comments)
