Here's the code int rem_dup(int n) { int *a,i,c,t,d,count[10]={0},arr[20],j=0,sum=0; a=(int *)malloc(sizeof(a)); for(i=0;n>0;i++)//storing each digit of number in an array { a[i]=n%10; n=n/10; } c=d=i-1; i=0; while(i<c)//reversing the array { t=a[i]; a[i++]=a[c]; a[c--]=t; } for(i=0;i<=d;i++)//setting repeated digits to -1 { if(count[a[i]]==0) count[a[i]]++; else a[i]=-1; } for(i=0,j=0;i<=d;i++) //storing all non repeating digits in anothor array arr[] { if(a[i]!=-1) { arr[j]=a[i]; j++; } } for(i=0;i<j;i++) sum=sum+arr[i]*power(10,j-i-1); return sum; }
