You're not doing that, you're just incrementing the field variable and trying again (which will cause you to search each index twice until you find the item or segfault by running past the end of the list). I'm practicing an interview algorithm, now coding it in Go. astrophysics and cosmology. public class BinarySearch { /** Use binary search to find the key in the list */ public static int binarySearch(int [] list, int key) { int low = 0; int high = list.length - … First off, your for loop is useless, since each branch in the conditional tree has a return statement in it, so it can never run more than one iteration. Thanks for contributing an answer to Stack Overflow! My latest research focus on gravitational lensing, astrophysical gravitational waves, and cosmology.

Chapter 19 Binary Search Trees Section 19.2 Binary Trees 19.1 A __________ (with no duplicate elements) has the property that for every node in the tree the value of any node in its left subtree is less than the value of the node and the value of any node in its right subtree is greater than the value of the node. This algorithm is more efficient than Cohen–Sutherland line clipping algorithm and can be extended to 3-Dimensional clipping. Currently I am a Bahcall Postdoctoral Fellow at the Institute for Advanced Study, and was externally supported by the NASA Einstein Fellowship for the first three years of my appointment. How do I legally resign in Germany when no one is at the office? To do binary search you need to keep track of the lowIndex, the lowest possible location the number could be at, and the highIndex, the highest possible location.
