Answer 1

Few changes, I copypaste only that parts.

//initialize flag to 0
int flag=0;

...

for(int i=0;i<l;i++)//comparing
{
// look only after each i, then you don't need the continue part
for(int j=i+1;j<l;j++)
{
if (str[i]==str[j])
{
// only if repetition set to true
flag=1;
}

}
}
if (flag) // flag should be true if duplicate
printf("Deja Vu");
else
printf("Unique");
