A storage location in the computer's memory that can hold a piece of data is called

which one of the following will reach every element in the array a? 1. for(int i = 0; i <= a.length; i++) 2. for(int i = 0; i

andrey2020 [161]

Answer:

You can simplify the problem down by recognizing that you just need to keep track of the integers you've seen in array that your given. You also need to account for edge cases for when the array is empty or the value you get would be greater than your max allowed value. Finally, you need to ensure O(n) complexity, you can't keep looping for every value you come across. This is where the boolean array comes in handy. See below -

public static int solution(int[] A)

{

int min = 1;

int max = 100000;

boolean[] vals = new boolean[max+1];

if(A.length == 0)

return min;

//mark the vals array with the integers we have seen in the A[]

for(int i = 0; i < A.length; i++)

{

if(A[i] < max + 1)

vals[A[i]] = true;

}

//start at our min val and loop until we come across a value we have not seen in A[]

for (int i = 1; i < max; i++)

{

if(vals[i] && min == i)

min++;

else if(!vals[i])

break;

}

if(min > max)

return max;

return min;

}

Create a java class for Bank Accounts with these public String attributes: ownerName, acctNbr and these private double attribute

Readme [11.4K]

Answer:

public class BankAccounts

{

public String ownerName;

public String acctNbr;

private double debits;

private double credits;

public BankAccounts(String ownerNm, String acNum)

{

debits = 0;

credits = 0;

ownerName = ownerNm;

acctNbr = acNum;

}

public void addDebit(double debitAmt)

{

if(credits > (debits + debitAmt))

debits = debits + debitAmt;

else

System.out.println("Insufficient balance");

}

public void addCredit(double creditAmt)

{

credits = credits + creditAmt;

}

public double getBalance()

{

double balance = 0;

if((credits - debits) > 0) // return the value if there is actually some balance left.

balance = credits - debits;

return balance; //returns 0 if credits are lesser or equal to debits

}

Explanation:

Here class name is BankAccounts which can be used to create a new bank account whenever any user wants to open a bank account. This class will help to track any new account opening, debits and credits operations carried out on that account.

We have a constructor here, which accepts 2 arguments i.e. Bank account Owner Name and Account Number. The constructor also sets the values of debits and credits as 0.

The methods addDebit(), addCredit() and getBalance() help to perform Debit and Credit operations on the account.

NOTE: The method getBalance() returns a positive value only when credits are greater than debits.

The method addDebits() can add debits only as the condition that the credits are greater than the resultant debits.

The code for class BankAccounts is hereby attached.

2) etc - etc file is the configuration file that they are local in the machines. When the program run these file are stored in the directories. this can be static and do not executable directory.

3) Boot - Boot file are stored in the directory which required processing of linux boot and such files are included in the linux kernel of the file.

Create a new class MyArray_DE and copy and paste the previous program. Be sure to rename the class to MyArray_DE. Modify the pro

vova2212 [387]

Answer:

public class MyArray_DE

{

public static void main(String[] args) {

int[] numbers = {28, 7, 92, 0, 100, 77};

int total = 0;

for (int i=0; i<numbers.length; i++){

if(numbers[i] % 2 == 0)

total += numbers[i];

}

System.out.println("The sum of even numbers is " + total);

System.out.println("The numbers in reverse is ");

for (int i=numbers.length-1; i>=0; i--){

System.out.print(numbers[i] + " ");

}

Explanation:

Since you did not provide the previous code, so I initialized an array named numbers

Initialize the total as 0

Create a for loop that iterates through the numbers

Inside the loop, if the number % 2 is equal to 0 (That means it is an even number), add the number to total (cumulative sum)

When the loop is done, print the total

Create another for loop that iterates through the numbers array and print the numbers in reverse order. Note that to print the numbers in reverse order, start the i from the last index of the array and decrease it until it reaches 0.
