[Solved] Python recursion facts

by

1) A recursive solution has a few benefits. Generally it is more readable, and smaller in terms of lines of code. When it doesn’t work, it’s almost always harder to debug. It’s usually preferable when it runs faster than a non-recursive solution (see merge sort). 2) By definition. 3) True — the point of recursion … Read more

[Solved] Php Calculating two functions [closed]

by

You can’t access $dine in your second function because it’s nowhere defined. The $dine from your first function is only a local variable. I would suggest this solution which uses the fact that calculate_dinein_price() also returns the value of $dine: public function calculate_dinein_total(){ $total_dine = 0.00; $total_dine = $total_dine + $this->calculate_dinein_price(); return $total_dine; } 8 … Read more

[Solved] What affects the time for a function to return to the caller. [closed]

by

The time returning from a function should be negligible. Most processors have the instruction for returning from a function optimized, usually one instruction. If you are returning an object via copy, the return time depends on the time required to copy the object. Essentially, a return from function involves obtaining the return address, then setting … Read more

[Solved] Write a function that returns avg arrival delay by carrier by airport in R

by

This is what I was looking for avgDelay <- function(carrier, dest) { TempTotal = 0 TempCount = 0 for(i in 1:dim(delays)[1]) { if(delays$CARRIER[i] == carrier & delays$ARR_DELAY[i] >0 & is.na(delays$ARR_DELAY[i]) == FALSE & delays$DEST[i] == dest) { TempTotal <-TempTotal + delays$ARR_DELAY[i] TempCount <-TempCount + 1 # keeps count of the number of delays } } … Read more

[Solved] Issue in taking character input to C program

by

You can’t use strcasecmp to compare characters. It’s not completely wrong, but a single character is not a properly terminated string. If you must do comparison this way, use strncasecmp: if(strncasecmp(&gender,&word_M, 1) == 0) That will limit it to comparing one character. Also, your retry loop doesn’t check for ‘F’, but checks ‘M’ twice. solved … Read more

[Solved] How do I do my homework with Arrays, Functions and Binary Search? [closed]

by

For a start, here is the original ArregloBinario class with the spacing fixed up: package laboratorio9; import java.util.Random; import java.util.Arrays; public class ArregloBinario { private int[] datos; private static Random generador = new Random(); public ArregloBinario (int tamanio) { datos = new int[tamanio]; for (int i=0; i<tamanio; i++) datos[i] = 10 + generador.nextInt(90); Arrays.sort(datos); } … Read more

[Solved] Code usability in c++ [closed]

by

Yes of course it is. How to make it happen depends on what these two files are (header files or main code files). Let’s call them function_defined.___ and function_used.___. There are two cases, depending on what each is. function_defined.hpp The simplest case — In function_defined.hpp, put int funct(int argument) {return 1} and in function_used.(c/h)pp, just … Read more

[Solved] does cout before return statement of recursive function stops it?

by

The body of an if-statement can be either a compound statement, which is a list of statements surrounded by {}, or it is the single statement following the if‘s condition. That means that this code: if(n>=2) cout<<“number of times the function called: “<<endl; return n*factorial(n-1); is completely equivalent to: if(n>=2){ cout<<“number of times the function … Read more

[Solved] To check whether my list fulfils the parameters set out in nested loop in scala function

by

You can use pattern matching to determine which type of Array you’re dealing with. def arrTest[A](a :Array[A]) :Boolean = a match { case sa :Array[String] => sa.length < 2 || sa.sliding(2).forall(x => x(0) < x(1)) case ia :Array[Int] => ia.length > 2 && ia(0) == 1 && ia(1) == 1 && ia.sliding(3).forall(x => x(0) + … Read more
