Largest of two distinct numbers without using any conditional statements or operators
In this problem set, we will be given any two distinct positive numbers, let’s say a and b, we need to return the largest of two distinct numbers without using any conditional statements (if-else) or any operators(, ==, !=, etc.) in c++. The main difficulty of the problem includes that we need to determine the largest of any two distinct positive numbers without using any operators or conditional statements. For example, INPUT: x=12, y=20 OUTPUT: 20 INPUT: x=3, y=2 OUTPUT: 3 Below is the algorithm that we will be using to solve this problem. Algorithm We will use type casting ...
Read MoreFind the Smallest Positive Number Missing From an Unsorted Array
Our objective is to find the smallest positive number that is missing from an unsorted array. We will be given an array a[] of both positive and negative numbers, we need to get the smallest positive number that is missing from an unsorted array in this problem. We can modify the array given in this problem to solve it. For example, INPUT : a[] = {5, 8, -13, 0, 18, 1, 3} OUTPUT : 2 INPUT : a[] = {7, 10, -8, 1, 4} OUTPUT : 2 In the above examples, we are given an unsorted array as an input. ...
Read MoreDivide two integers without using multiplication, division and mod operator
In this problem, we simply need to divide two integers without using multiplication, division and mod operator. Though we can use addition or multiplication or bit manipulation. The problem statement states that we will be given two integers x and y. Without using multiplication, division or mod operator, we need to determine the quotient after dividing x by y. Example INPUT: x=15 , y=5 OUTPUT: 3 INPUT: x=10 , y=4 OUTPUT: 2 INPUT: x=-20 , y=3 OUTPUT: -6 Approach Approach-1(using simple mathematics) In this approach, we will use a simple mathematics algorithm. Below is the step-by-step illustration of the ...
Read MoreCentered Dodecagonal Number
A figurative number that depicts a dodecagon is called a dodecagonal number. The Centered Dodecagonal number is represented by a dot in the centre and other dots encircling it in the successive dodecagonal (i.e. a 12-sided polygon) layers. Centered Dodecagonal number can be better explained with the below figure. For n=1, only a single dot will be there in the centre. So the output will be 1. For n=2, a single dot in the centre followed by a dodecagon encircling it. Thus, the total number of dots will be 13. So the next centred dodecagonal number ...
