Answer #1

When we use the MBED compiler the above statement is false.

An online compiler does not access your computer's local memory, all the runnning process takes place on a remote machine. If we use IDE's in the computer it can allocate dynamically memmory to the array and it can set value as null.But in online IDE's it uses the micro controller memmory, it is a low memmory and it has minimum memmory requirements. So it uses the existed memmory again and again by updating the memmory or override the memmory space.

Dynamic memmory allocation is take place in heap memmory and static memmory allocation is take place in stack memmory.But in MBED there is no such memmory systems it only have micro controller memmory. So it cannot set the values of array as null.It only override or update the memmory of its own again and again.

Given a large array of several million elements of type 'double', you are asked to sort them in ascending order using an algorithm of your choice. You choose selection sort. Why is this a poor choice? Group of answer choices Selection sort can only sort elements of type 'int' Selection sort requires 3x the memory of other sort algorithms Selection sort can only work on an array with an odd number of elements Selection sort will be prohibitively inefficient for...

Create a function that returns a boolean value if all-elements are not odd or even. Using Dr. Racket and the How to Design a Function (HtDF ) recipe, create a function that will return the following check-expect: (check-expect (all-elements? even? (list 1 2 3) false) (check-expect (all-elements? even? (list 2 4 6) true) (check-expect (all-elements? odd? (list 1 3 5) true) Can you find an element in the list where the predicate fails (return false)?
Why is the test size equal to the false discovery rate only when the null hypothesis...
Why is the test size equal to the false discovery rate only when the null hypothesis is correct? I may be misunderstanding what test size means. Also, is the false discover rate just the number of type 1 errors divided by the total number of rejected null hypotheses? If a set of rejected null hypotheses was rejected under a test of a 5% size, does this mean that out of all these hypotheses only 5% of them are actually true?...
