I think result may vary depending on which processor and which language you’re using. This because float numbers (in general) are stored with a number of bits that try to represent that fractional number, but there can be some (very little) difference. So when you do (d1-d2) you probably get a number really close to … Read more
My solutions was accepted by interview street. Firstly, my solutions wasn’t accepted, but after saw @Reinardus Surya Pradhit post, i realized, if pair (x, y) will be count twice, so i change it a litter bit and got success I will not post my solution here, but i can tell you the test case for … Read more
A simple test for whether some integer N is a Fibonacci number is as follows: N is a Fibonacci number iff either (5 * n^2 + 4) or (5 * n^2 – 4) is a square number. See here for the ingenious proof (page 417): http://www.fq.math.ca/Scanned/10-4/advanced10-4.pdf If it turns out that N is not a … Read more

[EDIT] So based on you’re edit i thought this solution. Since you don’t specify any programming language i’ll use some c-like functional programming. I’ll leave you the work of transforming it to object oriented if you need it. Input: Global maxtrix that starts in M[0,0] and ends in M[100’000, 100’000] (Note that, to make it … Read more
You can reformulate the question y = sqrt(x) as to find the value for y such that y*y – x equals zero. The easiest way to solve that equation is by doing a bisection on y (http://en.wikipedia.org/wiki/Bisection_method) between 0 and x (because 0 <= sqrt(x) <= x for all real numbers x where x should … Read more
To get a column number (or, more precisely, “left 3 or right 3”) subtract 1 and do a % modulus operator: (value-1) % 6. The result will be 0..2 (or “left column”) or 3..5 (so “right column”). 1 solved how to check number in range with n level
In the line $open = fopen(“http://quote.yahoo.com/d/quotes.csv?s=$symbol&f=sl1d1t1c1ohgv&e=.csv”, “r”); You need to substitute the actual symbol, not leave it as a string in the query. Maybe something like this: $open = fopen(“http://quote.yahoo.com/d/quotes.csv?s=”.$symbol.”&f=sl1d1t1c1ohgv&e=.csv”, “r”); to concatenate the symbol will help. If you have an invalid request, you are probably looking at garbage. Also – you need to make … Read more

So you have power of 2 operations which can be easily converted to bit operations… no bigint lib is needed for such triviality. Let assume you got number const int n=1000000000; // number size in bytes BYTE x[n]; // number bytes let num[0] be LSW (least signifficant Word) So the operations involved are: mod: y … Read more
