I solved the problem 140 the same way as 146, so I think it can be placed here as well.

Yes? What makes you to think so? Because it is not

I'll try to find the source code.
But I'm pretty sure that I'm using sorting method instead of combination

I second that ... I'm using a sorting method as well. But I guess there's probably more than one way to solve this problem. It all depends on your approach ...

[c]
#include<stdio.h>
#include<string.h>
int i,j,k,l;
char a[60],temp;
void main(){
while(1){
scanf("%s",&a);
l=strlen(a);
if(a[0]=='#'){break;}
for(i=l-2;i>=0;i--){
k=i;
for(j=i+1,temp='{';j<l;j++){
if(a[j]>a&&a[j]<temp){k=j;temp=a[j];}
}
if(k!=i){a[k]=a;a=temp;break;}
}
if(i>-1){
for(j=i+1;j<l-1;j++){
k=j;
for(i=j+1;i<l;i++){
if(a<a[k]){k=i;}
}
if(k!=j){temp=a[k];a[k]=a[j];a[j]=temp;}
}
}
if(i>-1){printf("%s\n",a);}
else{printf("No Successor\n");}
}
}
[/c]
That's the code.
