![Create a variable total of type Double set to 0. Then loop through the dictionary, and add the value of each integer and double to your variable's value. For each string value, add 1 to the
total. For each boolean, add 2 to the total if the boolean is true, or subtract 3 if it's false. Print the value of total.
Create a variable total2 of type Double set to 0. Loop through the collection again, adding up all the integers and doubles. For each string that you come across during the loop, attempt
to convert the string into a number, and add that value to the total. Ignore booleans. Print the total.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbea0901b-9b71-43dc-90d5-d9e10ed3de89%2Ffcb588a3-ba60-47ea-9b3a-e9a5762a2ac9%2Fsugvkx_processed.png&w=3840&q=75)
