### DATA STRUCTURE Code PRACTICE (DSA)

DATA STRUCTURE CODE PRACTICE : Data Structure is a way to store and organize data so that it can be used efficiently . For example, we can store a list of items using array,linked list,stack,queue,tree,graph. Fibonacci series ---------------------------------------------------------------------- #include <iostream> using namespace std; int main() { int n=10; int a=0,b=1; cout<<a<<" "<< b<<" "; for(int i=1;i<=10;i++){ int nextNumber=a+b; cout<<nextNumber<<" "; a=b; b=nextNumber; } } Prime Number --------------------------------------------------------------------------------- #include <iostream> using namespace std; int main() { int n=7; bool isPrime=0; for(int i=2;i<n;i++){ if(n%i==0){ isPrime=1; break; //bcz if it not prime we need to break } } if(isPrime){ cout&
