algorithm

sample job interview question. 3 people with luggage crossing river with one boat

computer programming bachelor's degree has calculus and other math

graduate schools just studying algorithim and probably dont even use a computer

could you tell me about your learning programming and relevent work experience using algorithms and why math is needed at school

sample job interview question. 3 people with luggage crossing river with one boat That is a typical white board reasoning https://en.wikipedia.org/wiki/Missionaries_and_cannibals_problem

Programming is more about breaking down a problem into very tiny items and stringing those items into a program that does work.

Hi rgb192,

why math is needed at school :

-Logic and critical thinking skills.
-The ability to identify and analyze patterns.
-Ability to see relationships .
-Problem solving skills.

Note:  Math is necessary for even the most basic of life functions.Whether you're buying groceries, determining a budget for yourself, calculating interest on investments etc.. math will somehow be involved.

Without it, great reliable, stable cathedrals could not be built, and wars would be lost.

I had also heard that, without math and relativity theory (very heavy in math), we would not be able to adjust for relativistic effects on getting accurate GPS readings for our car's navigation system.",

but then I came across this, and do not have time to evaluate it:

I don't know for sure whether an oil or watercolor artist needs any math unless they are interested in the theory of colors and hues and saturation. Or if they like puzzles, as apparently, one artist does:

A research scientist gave me state of the art image processing algorithms derived from radar input, and I had to implement them in a fast-running program.

You are stating a fact. Is there an implied question here?
In this MIT algorithms course, I don't recall seeing any code. There was pseudo code that a programmer could use to implement the algorithm, and there was complexity analysis that was a  major emphasis in developing the algorithms.

Really, I believe there is no need to tell anyone that math is the must if you go to programming.

What is computer algorithm you can read here:What Is a Programming Algorithm? . Again, understanding and implementing algorithms is the main programmer's job, in essence.
If you think, even a simple loop is an algorithm: take a next element from a collection, do something to the element, proceed until some condition is satisfied, stop.

Often you need to convert some manufacturing process algorithm or a user case to code. Like, e.g., user fills some form: display a form, wait for button Done click, validate fields, if OK - save and display success message, if not - display error message. Etc.

So, everything is about math and algorithms...
