Individually Delete sObject records in Visualforce Page using concept of Wrapper Class

-
Wrapper Class means a class inside another class.
Definition--

 A wrapper class is a class whose instances are the collection of other objects.
Wrapper class is used to display different object on a visualforce page in the same table

 Scenario is like this when we create a contact record in visualforce page, then VF page show recently created record like this--



 First the controller

 public with sharing class SingleRecordDelete {

     public String fname {get;set;}
    public String lname {get;set;}
    public String did {get;set;}
    
    public List<ContactWrp> crp {get;set;}
    
    public SingleRecordDelete(){
        crp = new List<ContactWrp>();
        
    }
    
    public void save(){
      Contact c = new Contact();
      c.firstname = fname;
      c.lastname = lname;
      insert c;
      crp.add(new ContactWrp(c));
      fname='';
      lname='';
    }
    
    public void doDelete()
    {
        List<Contact> contactToBeDelete = new List<Contact>();
        Contact cod = [select id from Contact where id =: did];
        contactToBeDelete.add(cod);
        if(contactToBeDelete.size()>0){
            delete contactToBeDelete;
        }
    }
    
     public class ContactWrp{
    
      public Contact cn {get;set;}
      
        public ContactWrp(Contact cs){
            this.cn = cs;                   
        }
    }

 }

 VisualforcePage--

 <apex:page controller="SingleRecordDelete">
  <apex:form >
     <apex:pageBlock title="Contacts">
          <apex:pageBlockSection title="New Contact" columns="2" id="fresh">
              <apex:inputText label="FirstName" value="{!fname}" />
              <apex:inputText label="LastName" value="{!lname}"/>
              <apex:commandButton action="{!save}" value="Save" reRender="lab,fresh"/>
          </apex:pageBlockSection> 
         
          <apex:pageBlockSection title="ContactList" id="lab">
              <apex:pageBlockTable value="{!crp}" var="cy" id="update">
                  <apex:column headerValue="FirstName">
                      <apex:outputLabel value="{!cy.cn.firstname}"/>
                  </apex:column>
                  
                  <apex:column headerValue="LastName">
                      <apex:outputLabel value="{!cy.cn.lastname}"/>
                  </apex:column>
                  
                  <apex:column >
                      <apex:commandLink value="Delete" action="{!doDelete}" style="color:Red" reRender="update">
                          <apex:param name="did" value="{!cy.cn.id}" assignTo="{!did}"/>
                      </apex:commandLink>
                  </apex:column>
                  
              </apex:pageBlockTable>
                  
          </apex:pageBlockSection>               
     </apex:pageBlock>
  </apex:form>
</apex:page>
Output looks like this---

VF Page--- < <apex:page standardController="Contact">   <apex:form id="frm">       <apex:pageBlock >           <apex:pageBlockSection >               <apex:inputField value="{!contact.LeadSource}">                   <apex:actionSupport event="onchange" reRender="frm"/>               </apex:inputField>            </apex:pageBlockSection>      ...
