Programming Riddles

Re: Programming Riddles

Ok I wrote this small function to find anagrams . Anyone with better algo ?

private static bool IsAnagrams(string one, string two)
        {
            Dictionary<char, int> dictionaryOne = new Dictionary<char, int>();
            Dictionary<char, int> dictionaryTwo = new Dictionary<char, int>();


            if (one.Length != two.Length) return false;


            foreach (var c in one)
            {
                dictionaryOne[c] = dictionaryOne.ContainsKey(c) ? dictionaryOne[c] + 1 : 1;
            }


            foreach (var c in two)
            {
                dictionaryTwo[c] = dictionaryTwo.ContainsKey(c) ? dictionaryTwo[c] + 1 : 1;
            }


            foreach (var item in dictionaryOne)
            {
                if (item.Value != dictionaryTwo[item.Key]) return false;
            }


            return true;
        }

Ok so I just realized that in C# using pure LINQ we can write one liner to achieve the same results .

Here you go … enjoy

private static bool IsAnagrams(string one, string two)
{
                  return one                    
                    .ToLower()
                    .ToCharArray()
                    .OrderBy(o => o)
                    .SequenceEqual(
                        two
                        .ToLower()
                        .ToCharArray()
                        .OrderBy(o => o)
                        );
}

Re: Programming Riddles

I think these for loops will work. One for the upper half and other for the lower half.

for (int i = 1; i < 10; i += 2) 

{

for (int j = 0; j < 9 - i / 2; j++)

system.out.print (" ");

for (int j = 0; j < i; j++)

system.out.print ("*");
system.out.print ("
");

}

for (int i = 7; i > 0; i -= 2) 

{

for (int j = 0; j < 9 - i / 2; j++)
system.out.print(" ");

for (int j = 0; j < i; j++)
system.out.print("*");

system.out.print("
");

}

I guess this will work. starts with one star and increases 2 *s next line. goes upto 9 *s. and then the same odd number back to finish it.

This is the output

Good job.

Re: Programming Riddles

Here is something in python:

lines = "".join(("*" * y, " " * (w - (y * 2)), "*" * y)) for y in xrange(w / 2, 0, -1)]
print "
".join(lines + lines-2::-1])

Re: Programming Riddles

Great Joel . I never really worked with python so can you please explain the logic you are using . Thanks .

@JoelKhan

Here is something in python:

lines = "".join(("*" * y, " " * (w - (y * 2)), "*" * y)) for y in xrange(w / 2, 0, -1)]
print "

Re: Programming Riddles

Yeah I’ve never worked in python too so that was interesting. A little lecture on how and what happened there would be appreciated Joel.
