In JAVA please:

blagie [28]

Answer:

import java.util.Scanner;

public class ArraysKeyValue {

public static void main (String [] args) {

final int SIZE_LIST = 4;

int[] keysList = new int[SIZE_LIST];

int[] itemsList = new int[SIZE_LIST];

int i;

keysList[0] = 13;

keysList[1] = 47;

keysList[2] = 71;

keysList[3] = 59;

itemsList[0] = 12;

itemsList[1] = 36;

itemsList[2] = 72;

itemsList[3] = 54;

/* Your solution goes here */

for ( i = 0; i < SIZE_LIST; i++){

if (keysList[i]>50){

System.out.println(itemsList[i] + " "); } }

System.out.println("");

}

Explanation:

I will explain the whole program flow.

There are two arrays here

keysList and itemsList

The first list (keysList) contains the following elements:

13 element at first position of the array (0th index)

47 element at second position of the array (1st index)

71 element at third position of the array (2nd index)

59 element at fourth position of the array (3rd index)

The other list (itemsList) contains the following elements:

12 element at first position of the array (0th index)

36 element at second position of the array (1st index)

72 element at third position of the array (2nd index)

54 element at fourth position of the array (3rd index)

The size of the array elements is fixed which is 4 and is stored in the variable SIZE_LIST.

Then the loop starts. The loop contains a variable i which is initialized to 0. First it checks if the value of i is less than the size of the list. It is true as SIZE_LIST=4 and i=0.
So the program control enters the body of the loop.
In first iteration, IF condition checks if the i-th element of the keysList is greater than 50. As i=0 So the element at 0th index of the keysList is 13 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i increments by 1 so now i becomes 1.
In next iteration loop again checks if the value of i is less than the size of the list which is true again so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=1 So the element at 1st index of the keysList is 47 which is not greater than 50 so the body of IF statement will not execute as the condition evaluates to false. The value of i is incremented by 1 so now i becomes 2.

In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 2 which is less than SIZE_LIST so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=2 So the element at 2nd index of the keysList is 71 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 2 so the value at the index 2 of the itemsList is displayed in the output which is 72. Next value of i is incremented by 1 so now i becomes 3.

In next iteration loop again checks if the value of i is less than the size of the list which is true again as i= 3 which is less than SIZE_LIST so the body of the loop executes.

IF condition checks if the i-th element of the keysList is greater than 50. As i=3 So the element at 3rd index of the keysList is 59 which is greater than 50 so the body of IF statement is executed as the condition evaluates to true. So in the body of the IF statement there is a print statement which prints the i-th element of the itemsList. As i = 3 so the value at the index 3 of the itemsList is displayed in the output which is 54. Next value of i is incremented by 1 so now i becomes 4.

In next iteration loop again checks if the value of i is less than the size of the list which is now false as i=4 which is equal to the SIZE_LIST= 4. So the loop breaks.
So the output of the above program is:

72

54

fenix001 [56]

The format for the UPDATE command is the word UPDATE, followed by the name of the table to be updated. The next portion of the command consists of the word <u>SET</u>, followed by the name of the column to be updated, an equals sign, and the new value.

Explanation:

An Update Query is an action query (SQL statement) that changes a set of records according to criteria you specify.
The SQL UPDATE Query is used to modify the existing records in a table. You can use the WHERE clause with the UPDATE query to update the selected rows, otherwise all the rows would be affected.
Update Queries let you modify the values of a field or fields in a table.

<u>UPDATE Syntax </u>

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

UPDATE table_name SET column1 = value1, column2 = value2, etc WHERE condition;

table_name: name of the table
column1: name of first , second, third column....
value1: new value for first, second, third column....
condition: condition to select the rows for which the
values of columns needs to be updated.

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()

Explanation:

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

The frequency polygon is printed using #'s to represent the frequency of each list element
