Cracking the coding interview 9.6 Given a matrix in which each row and each column is sorted. write a method to find an element in it. implement a function to find whether an element exists in a two-dimensional array sorted by rows and columns. Idea: If the element to be searched is smaller than the leftmost element in a row or the rightmost element in a row, the

You are given a binary tree in which each node contains a value. design an algorithm to print all paths which sum up to that value. note that it can be any path in the tree-it does not have to start at the root. Ideas: Since the beginning of the path is not necessarily in the root, it is not enough to find all the paths starting from the root. Each node may start or end. If any node is used as the end node, It is pushed to the root node. If there is a sum of values in the path, it is a satisfyin

the problem. This is what the interviewer first wants to see. We recommend a book: Steven skiena's the Algorithm Design Manual 1) algorithm complexity analysis. you must know how to use big O to analyze algorithm complexity. if you do not know this, you will not be able to pass the interview. if you do not know, read the relevant chapter carefully. you can do it! 2) sorting algorithm. you need to k
