 #include <iostream> using namespace std; int main() { int n ; while(1) { cin>>n; if(n==42) { break; }      cout<<n<<endl; } return 0; }

 #include<iostream> #include<cmath> using namespace std; typedef long long l; bool prime(l ); int main(){ l t; cin>>t; while(t--){ l n,m,i; cin>>m>>n; for(i=m;i<=n;i++){   if(prime(i)){ cout<<i<<endl; } } cout<<endl; } } bool prime(l a){ if(a==1) return 0; for(l i=2;i*i<=a;i++){ if(a%i==0) return 0; } return 1; }

In order to find factorial of n and number zeros at the end of factorial decimal, i simply find prime factors (5) ,and find the count then the count is our required answer.  #include <iostream> using namespace std; typedef long long l; int zero(l ); int main() { l t; cin>>t; while(t--){ l n; cin>>n; cout<<zero(n)<<endl; } return 0; } int zero(l n){ l c=0; if(n<0) return 0; for(l i=5;n/i>=1;i=i*5){ c+=n/i; } return c; }

For this problem, when we use the languages like c++ , c it is going to show due to time or time limit exceded ,for getting solution i used python .  t=int(input()) while(t): n=int(input()) fact=1 for i in range(1,n+1): fact=fact*i print(fact) t=t-1 If you have any doubts comment below 👇

Types Of System Calls:                                                                   Types Of System Calls  * Process Control: . create process, terminate process • end, abort • load, execute • get process attributes, set process attributes • wait for time • wait event, signal event • allocate and free memory • Dump memory if error • Debugger for determining bugs, single step execution • Locks for managing access to shared data between processes   File Management:   • create file, delete file • open, close file • read, write, reposition • get and set file attributes  Device Management: • request device, release device • read, write, reposition • get device attributes, set device attributes • logically attach or detach devices  Information Maintanance: • get time or date, set time or date • get system data, set system data • get and set process, file, or device attributes  Communications: • create, delete communication connection • send, receive messages if message passing model
