No, it’s not ok – you should define the variables you use. If it’s not defined, it might be defined by, say, some other php script (assuming you have multiple in use, which is a common case). The way to clear up the error is to define variables used. 2 solved error_reporting(E_ALL); Says $key undefined
You miss the lines if grade != -1: numbers.append(grade) after grade = int(grade). This adds the grade to the list numbers. Review Use PEP8 (you can use pep8online.com) to check your code For unnamed input, I prefer “Largest is %i, smallest is %i” % (max(numbers), min(numbers)) You can use sum to sum up integers in … Read more
Solution: change palindrome to int palindrome ( int n,int base) { int isTrue = 1; int digitCount = digitCountBase(n,base); int power = intPow(base,digitCount-1); int original = n; while (n>0&& digitCount >0) { if (n%base != (original/power) % base &&digitCount!=1) { isTrue =0; return 0; } n=n/base; power = power /base; digitCount=digitCount-2; } return isTrue; } … Read more
Gauss’ R(1 + 5R(A – 1, 4) + 4R(A – 1, 100) + 6R(A – 1, 400), 7) should be equivalent to int week_day = (1 + 5 * (year – 1) % 4) + 4 * ((year – 1) % 100) + 6 * ((year – 1) % 400) % 7; 1 solved Calculating … Read more
If the item in the comboboxes correspond to the 2D array you would want to do something like this: var distance = miles[combotxtDeparture.SelectedIndex, combotxtDestination.SelectedIndex]; solved Arrays in visual basic Creating a program that deals with driving distance [closed]
1) how can I free my memory or increase the maximum used memory? Are you receiving an OutOfMemoryException and your memory isn’t filled up in your machine? This might be due to x86 compilation and you should change it to x64. 2) is there are any another way to get all my pictures to picture … Read more
What value will var_dump show that echo will not show? You cannot echo an array if you do so it will just print data type not the data, you can use var_dump to print complete structure and data of an array. $array = array(1,2,3); echo $array; //<—-only print the data type var_dump($array) //<—–print the complete … Read more
It was so simple to do with speakeasy ! That was what I needed. Solved. solved Node require 3rd party script
The bitwise shift operators are the right-shift operator (>>), which moves the bits of shift_expression to the right, and the left-shift operator (<<), which moves the bits of shift_expression to the left. There are also two complex operators that can be used to assign the value directly to the value on left. These are the … Read more
You can get the last two digits using the remainder operator, then use the digits as key of sorted: a = [311, 409, 305, 104, 301, 204, 101, 306, 313, 202, 303, 410, 401, 105, 407, 408] result = sorted(a, key=lambda x: (x % 100, x)) print(result) Output [101, 301, 401, 202, 303, 104, 204, … Read more
Looks like bigquery.NewClient returns a (*Client, error), so if you’re trying to encapsulate that, you can probably just write a function that returns a *bigquery.Client 3 solved How do you return a non primitive type variable in golang
In the line char ** domain[] = new char * [rows]; char ** domain[] tries to make an array of char **. If the compiler didn’t complain about not having a valid array size in the [] and you would have a 3D structure. You want just plain old char ** for a 2D structure, … Read more
One option to your expected output is to create a indexed array with the associative array below it. This will create this kind of array: array(4) { [0]=> array(1) { [203]=> int(1) } [1]=> array(1) { [204]=> int(2) } [2]=> array(1) { [203]=> int(2) } [3]=> array(1) { [205]=> int(1) } } This is not … Read more
Position of the first circle is described as x1 = x1_0 + vx1 * t y1 = y1_0 + vy1 * t where x10 is initial x-coordinate, vx1 is x-component of velocity vector, t is time. Make similar expression for the second circle center, build expression for squared distance and find time when squared distance … Read more
