Sorting Techniques : Selection Sort , Bubble Sort , Insertion Sort

Sorting Techniques 1. Selection Sort: Idea: The inner loop selects the minimum element in the unsorted array  and places the elements in increasing order. Time complexity: O(N 2 ) #include <iostream> using namespace std; int main() {     int n;     cin>>n;   int arr[n];    for(int i=0;i<n;i++){          cin>>arr[i];   }  for(int i=0;i<n-1;i++){       for(int j=i+1;j<n;j++){            if(arr[j]<arr[i]){                 int temp =arr[j];                  arr[j]=arr[i];             arr[i]=temp;           }           }      }for(int i=0;i<n;i++){       cout<<arr[i]<<" ";    }   return 0; } 2.

How to check if a number is prime in C++ | How to generate Armstrong numbers in C++?

How to check if a number is prime in C++  Prime Numbers Prime numbers are numbers which have only 2 distinct factors i.e 1 and the number itself. Eg. 2,3,5,7,19 etc. Ques1. Write a program to check if a number is prime or not. #include <iostream> #include<cmath> using namespace std; int main() { int n; cin>>n; bool flag=0; for(int i=2;i<=sqrt(n);i++){ if(n%i==0){ cout<<"Non-prime"<<endl; flag=1; break; } } if(flag==0){ cout<<"prime"<<endl; } return 0; } How to generate Armstrong numbers in C++ Armstrong Numbers Armstrong numbers are numbers which have their sum of cube of individual digits equal to the number itself. E.g 153 = 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153. #include <iostream> #include<math.h> using namespace std; int main() { int n; cin>>n; int sum=0; int originaln=n; while(n>0){ int lastdigit= n%10; sum+= pow(lastdigit,3); n=n/10; } if(sum==originaln){ cout<<"Armstrong number"...

Loops in C++ : What is loop and types of loop in C++?

 Loops In computer programming, loops are used to   repeat a block of code  . For example, let's say we want to show a message 1000times , Then instead of writing the print statement 1000 times, we can use a loop. Type of loops 1. For loop 2. While loop 3. Do while loop For loop  For loop uses an external variable to control the execution. A for loop takes into account the                                           Initialization Condition checking Incrementation In its syntax itself. The syntax is shown below:- For(initialization;condition;incrememt){ //body } While loop  Imagine we had to print “Hello World” 100 times or n-number of times. Would it be wise to write cout << “Hello World\n” 100  times. While loops help us automate this. Sometimes, the loop also uses an external initialization and incrementation logic to control how many times t...
