Bogosort simply shuffles a collection randomly until it is sorted. BogoSort is an ineffective algorithm based permutation and combination that's why it is known Permutation sort. BogoSort is very flop sorting technique which is also known as, shotgun sort, stupid sort, monkey sort, or slow sort. The algorithm successively generates permutations of its input until it finds one that is sorted.Input - 53421 Output - 12345ExplanationIn bogosort array will be consist of unsorted element checking if the array elements are in order, and if it is not, then change the position of array elements, by swapping the elements randomly, and ...

9’s complement and 10’s complement are used to make the arithmetic operations in digital system easier. These are used to make computational operations easier using complement implementation and usually trade hardware usage to the program.To obtain the 9’s complement of any number we have to subtract the number with (10n – 1) where n = number of digits in the number, or in a simpler manner we have to subtract each digit of the given decimal number from 9.10’s complement, it is relatively easy to find out the 10’s complement after finding out the 9’s complement of that number. We ... Read More

Given a number n, we need to find the average of the square of natural Numbers till n. For this we will first The squares of all the numbers till n. then we will add all these squares and divide them by the number n.Input 3 Output 4.666667Explanation12 + 22 + 32 = 1 + 4 + 9 = 14 14/3 = 4.666667Example#include using namespace std; int main() { long n , i, sum=0 ,d; n=3; for(i=1;i

Given an array which is a collection of non-negative number represented as an array of digits, add 1 to the number (increment the number represented by the digits ). The digits are stored such that the most significant digit is the first element of the array.To add 1 to the number represented by digitsGiven array from the end, addition means rounding of the last no 4 to 5.If the last elements 9, make it 0 and carry = 1.For the next iteration check carry and if it adds to 10, do the same as step 2.After adding carry, make carry ...

The acosh() is the inverse hyperbolic cosine function that returns the inverse hyperbolic cosine of the element passed as parameter. this dysfunction can be out operate over complete. all the it are in radians.To use this method over complex numbers in C plus plus we need to define a template which redefines the function over complex numbers.Syntax for the function that is used to calculate the inverse hyperbolic cosine of a complex number and Returns the value −template complex acosh (const complex& z );Now this method will take complex number as an input and returns the Arc hyperbolic cosine of ...

The asinh() function is a function of standard C++ library. The asinh(value) is an inverse hyperbolic sine that returns the value of sinh(x) where x is in radian.The function −asinh() ;Parameter to the function, inverse hyperbolic angle in radian . It can be negative, positive or zero. The parameter value can be double, float or long double.Return value − It returns the inverse hyperbolic sine value of the input value. The returned value is in radians.Lets see an example that shows the working of the function −Example#include using namespace std; int main() { double insinh = 75.0; double ... Read More

Symmetric Matrix − A matrix whose transpose is equal to the matrix itself. Then it is called a symmetric matrix.Skew-symmetric matrix − A matrix whose transpose is equal to the negative of the matrix, then it is called a skew-symmetric matrix.The sum of symmetric and skew-symmetric matrix is a square matrix. To find these matrices as the sum we have this formula.Let A be a square matrix. then, A = (½)*(A + A`)+ (½ )*(A - A`), A` is the transpose of the matrix.(½ )(A+ A`) is symmetric matrix.(½ )(A - A`) is a skew-symmetric matrix.Example#include using namespace std; ...

The sum of square-sums of the first n natural numbers is finding the sum of sum of squares upto n terms. This series finds the sum of each number upto n, and adds this sums to a sum variable.The sum of square-sum of first 4 natural numbers is −sum = (12) + (12 + 22 ) + (12 + 22 + 32) + (12 + 22 + 32 + 42 ) = 1 + 5 + 14 + 30 = 50There are two methods to find the sum of square-sum of first n natural numbers.1) Using the for loop.In this ...

The series of squares of first n odd numbers takes squares of of first n odd numbers in series.The series is: 1,9,25,49,81,121…The series can also be written as − 12, 32, 52, 72, 92, 112….The sum of this series has a mathematical formula −n(2n+1)(2n-1)/ 3= n(4n2 - 1)/3Lets take an example,Input: N = 4 Output: sum =Explanation12 + 32 + 52 + 72 = 1 +9+ 25 + 49 = 84Using formula, sum = 4(4(4)2- 1)/3 = 4(64-1)/3 = 4(63)/3 = 4*21 = 84 both these methods are good but the one using mathematical formula is better because it does not use looks which reduces its time complexity.Example#include int main() { int n = 8; int sum = 0; for (int i = 1; i

A Set is a collection of data elements. Subset of a set is a set formed by only the elements after parent set. for example, B is A subset of a if all elements of B exist in A.Here we need to find the sum of all subsets of a set found by first n natural numbers. this means I need to find all subsets that can be formed and then adding them. Let's take an example, N = 3Set = {1, 2, 3}subsets formed = { {1}, {2}, {3}, {1, 2}, {1, 3}, {2, 3}, {1, 2, 3, } ... Read More
