JAVA PROGRAM-

Find the smallest and largest number in m*n matrix and sort them in ascending order also print its row and column value.

SOLUTION:

import java.util.*;
class matrix
{
public static void main(String args[])
{  int p=0,smallest=4999,larger=0,maxr=0,maxc=0,minr=0,minc=0;     ////global varibles//////
Scanner sc=new Scanner(System.in);       ////input through 'util' package////
System.out.println("enter m*n");
int m=sc.nextInt();
int n=sc.nextInt();
int a[][]=new int[m][n];    ///creating m*n matrix///
int b[]=new int[1000];
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
a[i][j]=sc.nextInt();        ///input elements in matrix////
}
}
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
if(a[i][j]<smallest)      ////for checking the number is smaller or not/////
{
smallest=a[i][j];              ////storing the smaller number in new array////
maxr=i;                      ////storing the row of smaller number////
maxc=j;                     ////same as storing the column of smaller number////
}
if(a[i][j]>larger)                   ////for checking the number is larger or not/////
{
larger=a[i][j];                         ////storing the larger number in new array///
minr=i;                                   ////storing the row of larger number////
minc=j;                                    ////same as storing the column of column number////
}
}
}
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
b[p]=a[i][j];                    /////storing all the elements in single dimensional array///
p++;
}
}
for(int i=0;i<p;i++)
{
for(int j=0;j<p-i-1;j++)
{
if(b[j]>b[j+1])                      ////sort the elements in ascending order////
{
int temp=b[j];
b[j]=b[j+1];
b[j+1]=temp;
}
}
}
p=0;
for(int i=0;i<m;i++)
{
for(int j=0;j<n;j++)
{
System.out.print(b[p]+"\t");
p++;
}
System.out.println();
}
System.out.println("largest"+"="+larger);             /////for printing///
System.out.println("Row : "+minr);
System.out.println("Column : "+minc);
System.out.println("smallest"+"="+smallest);
System.out.println("Row : "+maxr);
System.out.println("Column : "+maxc);
}
}
