Answer 2

let may be you generated array already and declared elements of it..
then..
int count=1;
for(int i=0;i<n;I++)
{
  for(j=0;j,N;J==00
{
  If(a[i]==a[j])
{
 count=count+1;
}
print "element"+a[i]+"repeated for"+count+"times";
count=1;
}
} 
o/p:
let array e a[]={1,2,3,4,1,1,2,,3,3,3};
then 1 repeated for 3 times
2 repeated for 2times
3 repeated for 4 times...so on..:)
