Journal Entry: Conditional

When I hear the word "If" the first thing that comes to my mind is a supposition or question.

Examples: 

1. If she is going to a party, why she didn't buy a present?

2. If you heat ice, it melts.

3. If you need me, call me. I will be waiting for your call.

Journal entry

How do the programs on the computer know what the user wants to do next? Inother words, if you are surfing the web, how does the computer know what page to go to next?

The computer knows what the user wants to do next based on the programming system that the computer has. The computer  work with a specific language that make it follow what the user wants. With this specific language the computer help the user to surf save in the website that the user wants.

Exploring Computer Science: Unit 2 project:

 Find the addresses and distance

You have just been hired by Amazon to work with their logistics team. You and a team of four are tasked to carry out a fact finding exercise for their new drone delivery system. One of the problems is to determine the fastest and shortest routes for a single drone to deliver twenty 5lb packages in the Broward county area from an Amazon Service Depot. The drone can carry 20lbs at a time and can make 4 deliveries before returning to the service center for more packages. The drone can also fly for 50 miles before it needs to be recharged. It flies at 50 mph.

You and your team will use google maps to assist in this exercise.

1. Designate tasks among your team for this exercise

2. Find the location of all addresses provided (save and note these locations)

3. Create a solution or plan for making deliveries. Make a note of distances and keep in mind the capacity (weights, fuel and speed) of the drone.

4. Create a Minimum spanning tree map of your deliveries

5. Make a note of total distance and time the drone flies.

6. Do you think there is an algorithm using the coordinates that can be programed into the drone to make deliveries more efficient? Explain

Journal Entry: How high can you count with your ten fingers?

With ten fingers I can count as long as I can or need. If I need to count up to 100 I just use ( count)  ten times my fingers.

Hand Shake Problem 2

1- Read and understand the problem: *There are 20 people in the room (including me) * Each person must handshake one time, only one. * we need to find out how many handshakes will occur. 2- Make a solution ( how are we going to find the answer) * My group made a table. 3- Execute the plan.

*If n amount of students: the result will be n(n-1) \ 2 

Ex; n=4 

4(4-1) | 2 

3*4=12

12|2 = 6

Steps in the problem‐solving process

The fist thing that my group did was understand that we had to cut a ''candy bar" in 12 equal pieces.

2. We made a plan in which we were thinking how many time do we need to cut the candy bar to get 12 equal pieces; we take a sheet of paper to use it as the candy bar.

3. Then we figure out that we need to cut the candy bar 11 times to get 12 equal pieces; we measure each pieces to make sure that the pieces were all with the same measure.

4. To get the final result we took 25-30 minutes; we solve the problem (how many cuts we made to get 12 equal pieces). 

5. To get "N" pieces we just made an equation ( n-1); also we made a table to have a better solution to our problem.

Journal Entry: Candy bar activity

The numbers of break will be 11. I just cut the candy bar directly 11 times and at the end I get 12 pieces.  If I need n pieces I just need to do n-1.
