while-loop

问题 how can I make this into a while loop and output the same thing???? for x in range(56,120) : if (x < 57) : summation = 0 summation = x + summation if (x == 119) : print (“Sum of integers from 56 to 120 is”, summation) 回答1: summation = 0 start_val = 56 stop_val = 120 while start_val < stop_val: summation += start_val start_val += 1 print summation 回答2: There are various methods, but one of them is: x = 56 while x < 120: ... x += 1 回答3: sum = 0 x = 56 while x < 120: sum += x x += 1 print(sum)

问题 I have a store_credits_orders table and orders table. The output that I want is similar to this but based on Store Credit Order Date and Time and Store Order Date and Time : The code that I have tried so far: <?php $table = ''; $queryToGetStoreCredit = "SELECT * FROM store_credits_orders WHERE SCO_CustEmailAdd = '".$_SESSION["Customer"]["email"]."'"; $validate->Query($queryToGetStoreCredit); if ($validate->NumRows() >= 1) { while ($rows_sco = $validate->FetchAllDatas()) { $used = $i = 0;

问题 I'm in the process of creating a program that reads data from an external file, compares it with other data within the file then prints the results to a new external file.

Here is the code: public class WageCalculator { public static void main(String[] args) throws FileNotFoundException { Scanner input = new Scanner(new FileReader("TestData.txt")

问题 So I'm trying to find the longest repeat for a specific pattern thats given. My code so far looks like this, and is fairly close, however it does not fully give the wanted result: use warnings; use strict; my $DNA; $DNA = "ATATCCCACTGTAGATAGATAGAATATATATATATCCCAGCT" ; print "$DNA\n" ; print "The longest AT repeat is " . longestRepeat($DNA, "AT") . "\n" ; print "The longest TAGA repeat is " . longestRepeat($DNA, "TAGA") . "\n" ; print "The longest C repeat is " . longestRepeat($DNA, "C") . "\n

问题 I am new to loops and I coded a for loop already that prompts the user to input a phrase and the for loop prints out how many spaces, a's, e's ,s's, and t's there are.

I have already tried experimenting with my code to fix my errors (either an ongoing loop or no results) for over a week. Here is my code below and thank you in advance. import java
