(CNN) US Secretary of State Mike Pompeo has denounced President Nicolas Maduro's obstruction of aid deliveries to Venezuela as the actions of a "sick tyrant." 

At the call of opposition leader and the nation's selfdeclared interim president, Juan Guaido, foreign aid has been shipped to Venezuela in response to worsening food and medicine shortages.

Maduro, who has been in a standoff with Guaido for the presidency, denies that a humanitarian crisis exists in Venezuela and suggests that aid efforts are part of a US plot to orchestrate a coup.

After Guaido named Saturday as the deadline for the aid to cross the border, Maduro vowed to stop the supplies from coming into the country. At a large rally in Caracas on Saturday, he dared the opposition to call for elections and called Guaido a "clown" and a "US puppet."

Trucks carrying supplies were blocked at most spots Saturday. Witnesses said two trucks were set ablaze while attempting to cross into Venezuela from Colombia.

Witnesses who spoke to CNN said the trucks went up in flames as Venezuelan troops loyal to Maduro prevented the vehicles from crossing the border. CNN cannot independently confirm the incident or the circumstances of how the two trucks were set on fire. National Assembly Representative and Guaido supporter Adriana Pichardo told CNN that at least five people were also killed in clashes with Venezuelan security forces on Saturday. CNN cannot independently confirm the number of fatalities.

What is a Programming Algorithm?

So, what is a programming algorithm? You can think of a programming algorithm as a recipe that describes the exact steps needed for the computer to solve a problem or reach a goal. We've all seen food recipes - they list the ingredients needed and a set of steps for how to make the described meal. Well, an algorithm is just like that. In computer lingo, the word for a recipe is a procedure, and the ingredients are called inputs. Your computer looks at your procedure, follows it to the letter, and you get to see the results, which are called outputs. A programming algorithm describes how to do something, and your computer will do it exactly that way every time. Well, it will once you convert your algorithm into a language it understands! However, it's important to note that a programming algorithm is not computer code. It's written in simple English (or whatever the programmer speaks). It doesn't beat around the bush--it has a start, a middle, and an end. In fact, you will probably label the first step 'start' and the last step 'end.' It includes only what you need to carry out the task. It does not include anything unclear, often called ambiguous in computer lingo, that someone reading it might wonder about. It always leads to a solution and tries to be the most efficient solution we can think up. It's often a good idea to number the steps, but you don't have to. Instead of numbered steps, some folks use indentation and write in pseudocode, which is a semiprogramming language used to describe the steps in an algorithm. But, we won't use that here since simplicity is the main thing.
