How do you find the for loop with index?
You can access the index even without using enumerate(>
.
1.Using a for loop, iterate through the length of my_list .
2. Loop variable index starts from 0 in this case.
3. In each iteration, get the value of the list at the current index using the statement value = my_list[index] .
4. Print the value and index .

How do you break a forEach in Kotlin? 'break' and 'continue' in forEach in Kotlin
Break - This is a keyword that helps in terminating an iteration, once a given condition is met, while traversing through a collection.
Continue - This keyword helps to continue the iteration once a condition is fulfilled.
