Hi.. folks , got stucked in a small functionality of sample development

Note: as per my code all the rows are getting rendered, on clicking of the Edit button,but the requirement is ::
1)on  click of the Edit button, that particular row should have to change to input , how it can be acheived.
Controller :  
public class testingclass {

public string xmlstring{get;set;}
 public string testingval{get;set;}
 public List<string> lsttestingval{get;set;}
 public boolean  indexSel{get;set;}
 public boolean anyBooleanValue{get;set;}
 
 public testingclass(){
  anyBooleanValue =true;
  lsttestingval = new list<string>();
  lsttestingval.add('Red');
    lsttestingval.add('Blue');
    lsttestingval.add('Yellow');
    
  }
  
   public void edit(){
   
   anyBooleanValue =False;
   }
   
   public void delet(){
   
  system.debug(lsttestingval.size());
    }
  
}
V.f page: 
<apex:page controller="testingclass">
<apex:form >
    <table style="width:100%">
  <tr>
    <th>name</th>
    <th>Edit</th>
    <th>Delete</th>
  </tr>
<apex:variable var="cnt" value="{!0}" /> 
 <apex:repeat var="a" value="{!lsttestingval}"> 
 <tr>
     <td>
      <apex:outputPanel rendered="{!anyBooleanValue}" >{!a}</apex:outputPanel>
      <apex:outputPanel rendered="{!!anyBooleanValue}" ><apex:inputText /></apex:outputPanel>
      <!--<apex:outputPanel rendered="{!!anyBooleanValue && cnt == !indexSel}"><apex:inputText value="{!a}"/></apex:outputPanel> --->
     </td>
     <td><apex:commandbutton action="{!Edit}" value="Edit" /></td>
      <td><apex:commandbutton action="{!delet}" value="Delete" /></td>
      </tr>
      <apex:variable var="cnt" value="{!cnt+1}"/>

Here is working code:
Apex Controller: 
public with sharing class Tests {

    public String xmlstring{get;set;}
    public String testingval{get;set;}
    public List<String> lsttestingval{get;set;}
    public Boolean indexSel{get;set;}
    public Integer editRow{get;set;}
    public Integer deleteRow{get;set;}

    public Tests(){
        editRow = -1;
        deleteRow = -1;
        lsttestingval = new List<String>();
        lsttestingval.add('Red');
        lsttestingval.add('Blue');
        lsttestingval.add('Yellow');
    }

    public PageReference editItem(){
        System.debug('editRow: ' + editRow);
        return null;
    }

    public PageReference deleteItem(){
        System.debug('deleteRow: ' + deleteRow);
        lsttestingval.remove(deleteRow);
        System.debug(lsttestingval.size());
        return null;
    }
}

Play around the index of the edit button row, that we definitely need to use in rendering the input elements, so basically the input field rendering will be if the current button clicked and the current row index is same, also we need to store the Edit button row index as well to track the clicked row.
