In the book it's stated "Recall that (k^d / 2 ) *(k^d / 2 ) = kd" - page 109, 6th edition, explaining why bidirectional search is faster than breadth-first search.

I can't recall where this comes from.....I mean, trying to factor them using standard math/polynomial calculations it doesn't result in this.

Any help on this (probably very silly) question is appreciated.

Write a program to evaluate the value of the following real valued function.
f(x,y,z) = x^2 + y^3 + z^4 + (x + y)z
Your program should read x, y and z from the keyboard.

What kinds of topics should I prepare for, I have a programming interview with Google using R for a entry level quantitative analyst position.

On page 378, it explains a solution to a system design problem.

It says that the big O analysis of BFS is O(q^k).

Shouldn't it be O(k^q) instead? (Assuming that each person has k nodes and q is the length of the path. We'd have to go through k nodes per level and there are q levels, right?)

Working with TurboTax is hassle free experience, as it is one of the best applications for personal finance management. Technical issues are rare, especially issues like TurboTax is not opening, getting freeze, closing abruptly, etc. If you are facing these errors, you need to find the root causes behind such issues. There could be many possible causes, and thus it is indeed a critical task. Commonly, it has been seen that uninstalling and then reinstalling TurboTax resolves such errors. However, this trick may not work always, especially when you are encounter hardware or operating software related problems. Call customer support phone number for TurboTax to talk with executives on these problems.

Given a singly linked list l0; l1; l2; : : : ; ln-1, define the “zip” of the list to be
l0; ln-1; l1; ln-2; : : : i. Write the function that computes the
zip of a list, with the constraint that it uses O(1) space.

Hi Gayle,

I really like your book CTCI, in the six addition I think you could add to the page 68 example involving the quadratic formula, the only slightly optimized version that solves for d need to check for negative numbers before getting the cube root of a**3+b**3-c**3, and the code should also check to see if d exceeds the range of numbers checked , 1000 in your case.


Thanks,
Tom
