using Dynamic memory allocation,you can create large array size.

example:m=1000000,n=1000000
void enter(int m,int n)
{
int i,j;
long int c=0;


matrix=new long int*[m]; /*m is row size*/
for(i=m-1;i>=0;i--)
{
matrix[i]=new long int[n]; /*n is col size*/
for(j=0;j<n;j++)
{
matrix[i][j]=++c;
}
delete matrix[i];
}
}

There is a lucky draw held every day. if there is a winning number eg 1876,then all possible numbers like 1867,1687,1768 etc are the numbers that match irrespective of the position of the digit. Thus all these numbers qualify fr the lucky draw prize Assume there is no zero digit in any numbers. write a program to show all the possible winning numbers if a "winning number"is passed as an arguments to the function.
