A Peterson Graph Problem in C Program?
Suppose we have one graph like below. That graph is Peterson graph. The vertices are numbered from 0 through 9. Each vertex has some letters. Let consider one walk W, in that graph, where L vertices are used. A string S with L letters is realized by the walk W when the letter sequence in W and S are same. We can visit the vertices multiple times.For example, one string S is like “ABBECCD”, this is realized by the walk (0, 1, 6, 9, 7, 2, 3). Our task is to find such walk, and if that walk is present, ...
Read MoreA C/C++ Pointer Puzzle?
Suppose we have one integer variable whose size is 4 byte, another pointer variable is there, whose size is 8 bytes. So what will be the output of the following?Example#include using namespace std; main() { int a[4][5][6]; int x = 0; int* a1 = &x; int** a2 = &a1; int*** a3 = &a2; cout
Read More3-digit Osiris number C Program?
Here we will see the Osiris number. An Osiris number is such kind of number that are equal to the sum of permutations of sub-samples of their own digits. Suppose the number is 132. Then if we calculate {12 + 21 + 13 + 31 + 23 + 32} this is also 132. So the number is Osiris number. We have to check whether the given number is Osiris number or not.Approach is simple. If we analyze the numbers, each digit is occurring twice so they are in ones position and tens position. So we can check by multiplying 11 ...
Read MoreAdd 1 to a number represented as a linked list?
The linked list representation of a number is provided in such a way that the all nodes of the linked list are treated as one digit of the number. The node stores the number such that the first element of the linked list holds the most significant digit of the number, and the last element of the linked list holds the least significant bit of the number. For example, the number 202345 is represented in the linked list as (2->0->2->3->4->5).And to add one to this linked list represented number we have to check the value of the least significant bit ...
Read MoreC program to calculate the value of nPr?
Permutations, nPr can also be represented as P(n,r) is a mathematical formula to find the number of permutations. The formula of P(n, r) is n! / (n – r)!.The number of permutations on a set of n elements is given by n! where “!” represents factorial.Input:n=5;r=4; Output:120ExplanationP(5, 4) = 5! / (5-4)! => 120 / 1 = 120 5!=1*2*3*4*5*=120Example#include using namespace std; long int fact(int x) { int i, f=1; for(i=2; i
Read MoreC program to Find the Largest Number Among Three Numbers
This program takes the 3 numbers and finds the biggest among all. For this, we will compare the numbers with each other and find out which is the largestInput: a=2,b=4,c=7 Output:7 Largest NumberExplanationThis program uses only if statement to find the largest number.Example#include using namespace std; int main() { int a,b,c; a=2,b=4,c=7; if(a>b) { if(a>c) { printf("%d Largest Number ",a); } else { printf("%d Largest Number ",c); } } else { if(b>c) { printf("%d Largest Number ",b); } else { printf("%d Largest Number ",c); } } return 0; }
Read MoreC Program for the compound interest?
Compound interest is the simple interest that is compounded annually i.e. the interest will be calculated and added to the principal amount every year. This increases the overall interest as compared to simple interest. There is a different mathematical formula to calculate the compound interest. Lets see with the an example,Input:p=5, r=4, t=5 Output:1.083263ExplanationCompound Interest = Principle * (1 + Rate / 100)^time CI=5*(1+4/100)^5 CI=1.083263Example#include #include using namespace std; int main() { float p, r, t, ci; p=5; r=4; t=5; ci = p * pow((1 + r / 100), t) - p; printf("%f", ci); return 0; }
Read MoreC/C++ Program for the n-th Fibonacci number?
The Fibonacci sequence is a series where the next term is the sum of the previous two terms.The first two terms of the Fibonacci sequence is 0 followed by 1. In this problem, we will find the nth number in the Fibonacci series. For this we will calculate all the numbers and print the n terms.Input:8 Output:0 1 1 2 3 5 8 13Explanation0+1=1 1+1=2 1+2=3 2+3=5Using For loop to sum of previous two terms for next termExample#include using namespace std; int main() { int t1=0,t2=1,n,i,nextTerm; n = 8; for ( i = 1; i
Read More10’s Complement of a decimal number?
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 MoreAverage of Squares of n Natural Numbers?
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
