void validation(){

    int num1,num2;
    bool valid=false;
    while(valid==false){
    cout<<"Enter First number"<<endl;
    cin>>num1;
    cout<<"Enter second number"<<endl;
    cin>>num2;
    if((num1<num2) && (num1>=0)){
    
    valid=true;
    
    cout<<"first value="<<num1<<" second value="<<num2<<endl;    
    
    }else{
    
    
    cout<<"Entered wrong values:\n both values must be positive and first value must be less than second value\n try again"<<endl;
