The challenge is to display the pattern using one loop only and with continue statement.AlgorithSTART Step 1 -> declare start variables i and j to 0 with number of rows in n to 6 Step 2 -> Loop For i=1 and i

Given array with set of elements and the task is to find out set with exactly three elements having sum less than or equals to k.Input − arr[]= {1, 2, 3, 8, 5, 4}Output − set → {1, 2, 3} {1, 2, 5} {1, 2, 4} {1, 3, 5} {1, 3, 4} {1, 5, 4} {2, 3, 5} {2, 3, 4}In this, first task is to calculate the size of array depending upon which for loop of i is iterated till size-2 and for loop of j is iterated till size-1 and for loop of k is iterated till sizeAlgorithSTART Step 1 ...

There should be sequence of N 0’s and M 1’s such that the sequence so formed shouldn’t contain two consecutive 0’s with three consecutive 1’s.Input − N=5 M=9Output − 1 1 0 1 1 0 1 1 0 1 0 1 0 1Note − To make the above sequence, the statement (m < n-1) || m >= 2 * (n + 1) should be false if it is true than we can’t make the above sequence.It is advisable to first go through question logic and try yourself instead of jumping to the solution directly given below.AlgorithmSTART Step 1 -> take values in ...

Print the given numeric value as words. It’s easy to do with switch using cases from 0-9 but challenge is without using them.Input  − N=900Output − NINE ZERO ZEROIt is possible by creating array of pointers that contains 0-9 in words.AlgorithmSTART Step 1 -> declare int variables num, i and array of pointer char *alpha with values {"ZERO", "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT", "NINE"} Step 2 -> declare char array str[20] Step 3 -> call function itoa with parameters num, str, 10 Step 4 -> Loop For i=0 and str[i]!=’\o’ and i++    Print alpha[str[i] - '0'] ...

The program to find the area of a square inscribed in a circle which itself is inscribed in an equilateral triangle. The radius of circle inscribed inside an equilateral is a/(2√3).The diameter of circle is the diagonal of square, d = 2 * r = a/ √3 Area formula for area of square given its diagonals is ½ d2, A = 0.5 * d2 A = (1/2) * (a2) / (3) = (a2/6) Example#include using namespace std; int main() {    float area,a = 10;    area = (a*a) / 6;    cout

Fork() bomb is a Dos (Denial Of Service) attack against the linux based system. This calls the Fork() system infinite number of times that fills the memory of the program and intends to harm the system.Bash script for fork bomb:(){ :|: & };:The code explained as :( ) is function definition, { } defines the body of the loop. :|:& create a memory location and does not allow it to get deallocated. This program call itself multiple number of time again and again. Thus calling infinite calls.C Fork bomb is also the same type of Dos but it can be ... Read More

Counting the number of trailing zeroes in a factorial number is done by counting the number of 2s and 5s in the factors of the number. Because 2*5 gives 10 which is a trailing 0 in the factorial of a number.ExampleFactorial of 7 = 5040, the number of trailing 0’s is 1.Based on our logic 7! = 2*3*4*5*6*7, it has 3 2s and 1 5s so the number of trailing 0’s is 1.#include using namespace std; int main() {    int n = 45;    int count = 0;    for (int i = 5; n / i >= 1; i *= 5)       count += n / i;    cout
