Use a Binary Search on an int array sorted in descending order
Feb 2, 2015 · You can pass a reverse comparator in the binary search when you want to run the binary search in an array which is sorted in descending order. Example: Integer [] arr = new Integer[]{5,6,2,9,7}; Arrays.sort(arr, Collections.reverseOrder()); //sorting the array in descending order Arrays.binarySearch(arr, 2, Comparator.reverseOrder ...
c - Patterns in Binary Numbers - Stack Overflow
Oct 23, 2009 · Write a C program that reads integers n and m as input, and then prints out all n-bit binary numbers that contain the m-bit pattern. The binary numbers must be printed in ascending order. You are not allow to use strings, arrays or recursion for this question.
How can I print a binary tree search on DESCENDING order?
Nov 26, 2019 · What do I need to do to print it in descending order (just by manipulating that function) and get 5, 4, 3, 2, 1 as result? Just traverse Right -> root -> left. Property of binary search tree has the key for the answer. Going left-first means, going towards smallest value first in the current BST-subtree, so it gives sorted ascending order.
