unbiased random number generator using a biased one

you have a biased random number generator that produces a 1 with a probability p and 0 with a probability (1-p). you do not know the value of p. using this make an unbiased random number generator which produces 1 with a probability 0.5 and 0 with a probability 0.5. Note: this problem is an exercise problem from Introduction to Algorith...

What Math topics & resources to consider as beginner to indulge the book - Introduction to Algorithms (CLRS)?

I'm a programmer who's beginning to appreciate the knowledge & usability of Algorithms in my work as I move forward with my skill-set. I don't want to take the short path by learning how to apply algorithms "as-is" but would rather like to know the foundation and fundamentals behind them. For that I need Math, at which I'm pretty "basic"...

Is a node in a tree considered its own ancestor?

I'm wondering what the consensus is on the definition of "ancestor" in a computer science context. I only ask because in Introduction to Algorithms, Second Edition, p. 259 there is a description of the algorithm Tree-Successor(x) that seems odd. In finding the successor of node x, [...] if the right subtree of node x is empty and x ...

Linked-list representation of disjoint sets - omission in Intro to Algorithms text?

Having had success with my last CLRS question, here's another: In Introduction to Algorithms, Second Edition, p. 501-502, a linked-list representation of disjoint sets is described, wherein each list member the following three fields are maintained: set member pointer to next object pointer back to first object (the set representative...
