WRONG ANSWER IN AMBIGUOUS PERMUTATIONS

general
1

#include<stdio.h>
int main()
{
int nod,copy=0,num,pnum=0,pos=0,a=0;
scanf("%d %d",&nod,&num);
for(int i=1;i<=nod;i++)
{
pos=0;
copy=num;
while(copy!=0)
{
pos+=1;
a=copy%10;
if(i==a)
pnum=pnum*10+(nod-pos+1);
copy=copy/10;
}
}
if(pnum==num)
printf(“ambiguous”);
else
printf(“not ambiguous”);
printf("\n");
}

Please a) format your code (copying and posting it as-is gives code that doesn’t compile) and b) link to the problem so we don’t have to google it :slight_smile:

The first problem seems to be that you aren’t handling multiple testcases - the example input

4
1 4 3 2
5
2 3 4 5 1
1
1
0

should print out 3 different values:

ambiguous
not ambiguous
ambiguous

but yours only prints one.

I recommend that you get in the habit of running your program with the example input locally, and not submitting until (at least) that gives the correct answer :slight_smile:

Edit:

Once you’ve got the example input working, try this testcase where N is always 15

Testcase (N = 15)

15
12 7 13 10 11 6 2 14 15 4 5 1 3 8 9 
0

The results for this should be:
