(Enumerable.ElementAt) that uses an optimized code path if the given enumerable is backed by an IList. However, if indexing is used in a loop, a linear scan can have disastrous performance implications, because it will turn your nice O(n) algorithm into an O(n2) algorithm. ...
Vocabulary terms in mathematics can be tricky. The terms and words used in mathematics can sometimes have a different meaning than those same terms and words in everyday language, but they can also sometimes mean the same thing. Thus, being familiar with vocabulary in math is just as ...
What is algebraic expression and linear equation - Algebraic expression:An algebraic expression is an expression built from integer constants, variables, and algebraic operations (addition, subtraction, multiplication, division). For example, $3x^2 −
At first glance, this looks like a somewhat arbitrary problem (as many of Erdös’s problems initially do), as the function is not obviously related to any other well-known function or problem. However, it turns out that this problem is closely related to the parity barrier in sieve theor...
