Re: [algogeeks] DISTINCT Permutations ( Not Easy)

Hi Nishanth Pandey, I got it. If str[end] char is present in any index between [start, end) we would have already generated permutations with str[end] character in index start. So no need to generate those permutations again. Again, Thank you very much for your

Hi Nishanth Pandey, Excellent solution! It meets all requirements in problem! One thing I am finding hard to understand is your duplicate functions logic. code is simple. But reason behind it I am finding hard. I would write it like bool duplicate(char str[],

This will help u i guess : #include iostream #include string.h using namespace std; void swap(char str[],int m,int n ) { char temp=str[m]; str[m]=str[n]; str[n]=temp; } bool duplicate(char str[], int start, int end) { if(start == end) return false; else for(; startend; start++)
