181 | 
182 | In this exercise, you will create the code for a for loop, using the counter variable named i starting from 1.
183 | 
184 | To make the counter increment by 1 on each loop, you will use i++.
185 | 
186 | The exit condition for the for loop should match the output given below. 
187 | 
188 | Inside the loop, write an if-else statement, which will check the following conditions:
189 | 
190 | First, it will check if the value of i is 1. If it is, your code will console log the string "Gold medal".
191 | 
192 | Next, I will check if the value of i is 2. If it is, your code will console log the string "Silver medal".
193 | 
194 | Then, your code will check if the value of i is 3. If it is, it will console log the string "Bronze medal".
195 | 
196 | For all the remaining values of i, your code will console log just the value of i.
197 | 
198 | Note: The expected console log of the entire code should be as follows.
199 | Gold medal
200 | Silver medal
201 | Bronze medal
202 | 4
