Given a set S, generate all distinct subsets of it i.e., find distinct power set of set S. A power set of any set S is the set of all subsets of S, including the empty set and S itself.
Given an binary array of size two having alteast one element as zero, write a single line function to set both its elements to zero. Use of ternary operator and direct assignment of elements are not allowed.
Given an unsorted array of integers whose each element lies in range 0 to n-1 where n is the size of the array, rearrange array such that A[A[i]] is set to i for every element A[i] in the array.
Given a number, find out if it is even or odd without using any conditional statement (if-else) or ternary operator.
Given an array where all its elements are sorted except two elements which were swapped, sort the array in linear time. Assume there are no duplicates in the array.
In this post, we will see how to reverse a string in Java in 10 different ways. For example, reverse of “Techie Delight” is “thgileD eihceT”.
Given an array constructed from another array by taking sum of every distinct pair in it, decode the array to get back the original array elements.
Given two integers x and n where n is non-negative, efficiently compute the value of power function pow(x, n).
Given a MxN matrix, print matrix in spiral order.
Write a program to print all numbers between 1 to N without using semicolon.
Given two integers, swap them without using any third variable.
