Answer:
//here is code in Java.
import java.util.*;
class Main
{
public static void main (String[] args) throws java.lang.Exception
{
try{
// variable to store row and column size
int row_size,col_size;
Scanner inp=new Scanner(System.in);
System.out.print("How many rows?");
// read the row size
row_size=inp.nextInt();
System.out.print("How many columns?");
//read the column size
col_size=inp.nextInt();
// create an array of size rowxcolumn
int[][] mat=new int[row_size][col_size];
// array to store row max and column max
int max_of_row[]=new int[row_size];
int max_of_col[]=new int[col_size];
// read the elements of array
for(int x=0;x<row_size;x++)
{
int m=Integer.MIN_VALUE;
System.out.println("enter elements of row "+x+" separated by spaces:");
for(int y=0;y<col_size;y++)
{
// find the maximum of each row
mat[x][y]=inp.nextInt();
if(mat[x][y]>m)
m=mat[x][y];
}
max_of_row[x]=m;
}
// print the output in required format
System.out.println("Results:");
for(int a=0;a<row_size;a++)
{
for(int b=0;b<col_size;b++)
{
System.out.print(mat[a][b]+" ");
}
System.out.print("["+max_of_row[a]+"]");
System.out.println();
}
// find the maximum of each column
for(int x=0;x<col_size;x++)
{
int max_c =Integer.MIN_VALUE;
for(int y=0;y<row_size;y++)
{
if(mat[y][x]>max_c)
{
max_c=mat[y][x];
}
max_of_col[x]=max_c;
}
}
// print the max of each column
System.out.println("max of each col:");
for(int a=0;a<col_size;a++)
{
System.out.print("["+max_of_col[a]+"]"+" ");
}
}catch(Exception ex){
return;}
}
}
Explanation:
Read the number of row and column. Create an array of size rowxcolumn. Read the elements of the array and find the max of each row. Save the max of each row in an array. Find the max of each column and save it in another array.Print the required output.
Output:
How many rows?5
How many columns?4
enter elements of row 0 separated by spaces:
52 68 62 75
enter elements of row 1 separated by spaces:
88 52 -84 -68
enter elements of row 2 separated by spaces:
-24 51 -67 82
enter elements of row 3 separated by spaces:
14 78 61 97
enter elements of row 4 separated by spaces:
67 -11 4 47
Results:
52 68 62 75 [75]
88 52 -84 -68 [88]
-24 51 -67 82 [82]
14 78 61 97 [97]
67 -11 4 47 [67]
max of each col:
[88] [78] [62] [97]
