🔒 Closed Hayssss hanggang table lang mapiga ko kaphc

[Mauwanna0327]

Pano ba codes nito mga peeps

 

[JackFrost10]

2 dimensional array po yan,

box[0][0] ung first po is row ung second po is column meaning po mag gumawa ka ng table na 3x3 ang mga array mo is

-------------------------------------------------
| box[0][0] | box[0][1] | box[0][2] |
-------------------------------------------------
| box[1][0] | box[1][1] | box[1][2] |
-------------------------------------------------
| box[2][0] | box[2][1] | box[2][2] |
-------------------------------------------------

try ko lng maya eh code, medyo mahaba kasi,

 

[mrHazan]

Yes 2D int array with size 4 by 4.

try nyo po ito sir pag sumuko na kayo; konting loops lang po yan, kayo na po bahala sa diagonal

Simple solution para sa simple problem mo. Since array ang topic niyo use array.
Pag-aralan mo mabuti. Madali na yan intindihin.

Custom size table:

public class Problem01
{
    public static void main(String[] args)
    {
        Scanner userInput = new Scanner(System.in);
        
        int sizeRow;
        int sizeCol;
        int sumAll = 0;
        int sumEven = 0;
        int sumUnique = 0;
        boolean isUnique;
        int uniqueCounter = 0;

        System.out.print("Row Size: ");
        sizeRow = userInput.nextInt();
        System.out.print("Column Size: ");
        sizeCol = userInput.nextInt();
        
        int arrayInt[][] = new int[sizeRow][sizeCol];
        int uniqueInt[] = new int[sizeRow * sizeCol];
        
        //Get the inputs from user and get sum needed
        System.out.println("Put the " + sizeRow*sizeCol + " integers: ");
        for(int i = 0; i < sizeRow; i++)
        {
            for(int j = 0; j < sizeCol; j++)
            {
                arrayInt[i][j] = userInput.nextInt();
                sumAll += arrayInt[i][j];
                sumEven += ((arrayInt[i][j] % 2 == 0) ? arrayInt[i][j] : 0);
                
                //Check if unique, if yes add
                isUnique = true;
                for(int k = 0; k < uniqueCounter; k++)
                {
                    if(arrayInt[i][j] == uniqueInt[k])
                    {
                        isUnique = false;
                        break;
                    }
                }
                if(isUnique)
                {
                    uniqueInt[uniqueCounter] = arrayInt[i][j];
                    sumUnique += arrayInt[i][j];
                    uniqueCounter++;
                }
            }
        }
        
        System.out.println("Input: ");
        for(int i = 0; i < sizeRow; i++)
        {
            for(int j = 0; j < sizeCol; j++)
            {
                System.out.print(arrayInt[i][j] + "\t");
            }
            System.out.println("");
        }
        
        System.out.println("Sum of all integers: " + sumAll);
        System.out.println("Sum of all even: " + sumEven);
        System.out.println("Sum of all unique: " + sumUnique);
    }
    
}

Perfect size table:

public class Problem02
{
    public static void main(String[] args)
    {
        int sizeArray;
        Scanner userInput = new Scanner(System.in);
        
        System.out.print("Size: ");
        sizeArray = userInput.nextInt();
        
        int arrayInt[][] = new int[sizeArray][sizeArray];
        
        //Get the inputs from user
        System.out.println("Put the " + sizeArray*sizeArray + " integers: ");
        for(int i = 0; i < sizeArray; i++)
        {
            for(int j = 0; j < sizeArray; j++)
            {
                arrayInt[i][j] = userInput.nextInt();
            }
        }
        //Display the table
        System.out.println("Input: ");
        for(int i = 0; i < sizeArray; i++)
        {
            for(int j = 0; j < sizeArray; j++)
            {
                System.out.print(arrayInt[i][j] + "\t");
                
            }
            System.out.println("");
        }
        
        //Get the sum of 1st diagonal
        int firstDiagonalSum = 0;
        for(int i = 0; i < sizeArray; i++)
        {
            firstDiagonalSum += arrayInt[i][i];
        }
        System.out.println("\nSum of first diagonal: " + firstDiagonalSum);
        
        //Get the sum of 2nd diagonal
        int secondDiagonalSum = 0;
        for(int i = 0; i < sizeArray; i++)
        {
            secondDiagonalSum += arrayInt[i][(sizeArray-1) - i];
        }
        System.out.println("Sum of second diagonal: " + secondDiagonalSum);
    }
}

 

[haxxorisme]

hmm multi dimensional arrays. get position of the diagonal. tapos kunin mo yung numbers then total mo lahat.

Pano po yan sa oop sir?
