You basically need to compare a with both b and c (using Math.abs(a-b) and using Math.abs(a-c)) and then check if the other values differ by at least 2. Something like this: public static boolean closeFar(int a, int b, int c) { return ( (Math.abs(a-b) == 1 && (Math.abs(a-c) >= 2 && Math.abs(b-c) >= 2) || … Read more
The easiest way is to check how nums looks like after every operation (with print(nums) in scratch or calling it (nums) in terminal). Next time, try it yourself. In A: With the first line (nums[:k] = nums[len(nums)-k:]): nums = [5, 6, 7, 4, 5, 6, 7] – you’ve substituted nums[0:3] (1, 2, 3) with nums[4:7] … Read more
A string is an array of characters which end with \0. So printf() will not work. To output an array of characters you can use fwrite(). fwrite() has this declaration: size_t fwrite ( const void * ptr, size_t size, size_t count, FILE * stream ); ptr points to the data you want to output, size*count … Read more
As @Hitobat mentioned in commend – you have list with dictionary inside so you have to use [0] to get this dictionary. Or you have to use for-loop if you have more elements on list data = [{‘_id’: ‘5f563c1bf8eaa9d98eca231f’, ‘allEnabledDs’: None, ‘allEnabledIdSor’: None, ‘correlationFilterEntitySource’: True, ‘created_at’: ‘2020-09-07T13:56:43.469Z’, ‘dsConnectionList’: None, ‘folderToLabelMapping’: None, ‘idConnectionList’: None, ‘identityResolutionScan’: False, … Read more
You can get the numerical index of the last item with the documented index command, passing in the special string “end”: last_index = the_listbox.index(“end”) To get the value of the last item you can use “end” in the get method as well: last_value = the_listbox.get(“end”) To make sure that the last item in the listbox … Read more
Is Regex required? Here’s linq. edit: added a regex option as well since that was requested. ([a-z])([A-Z])”, “$1 $2”) matches lowercase letter and then uppercase letter and returns the matches as $1 and $2 respectively w/ a space in between. Note: this won’t work if you have accented characters like É, is that needed in … Read more

The difference between the two elements in a column is 9: a[i][j] = a[i-1][j] + 9, thus the code may be modified as: public static void main(String args[]) { int array[][] = new int[6][5]; // initialize the first row array[0] = new int[] {1, 2, 3, 5, 7}; // print the first row System.out.println(Arrays.toString(array[0])); for … Read more
The R.java file should be automatically generated by Android. Try the following: If you are using Eclipse try “project clean” to regenerate the file. Try to fix all errors not related to the R file and then retry the “project clean” option. Other errors (e.g. your xml layout files) can “stall” a new build of … Read more
Per comment of OP/modified question, if you want 1 or 2 digits, optionally followed by (a period, followed by 1 or 2 more digits), you could use this regex: var regex = /^\d{1,2}(\.\d{1,2})?$/; // The ( ) groups several things together sequentially. // The ? makes it optional. If you want 1 or 2 digits, … Read more
Depending upon what hashing you are using to store the password, your model confitions would be something like this: $this->db->select(‘*’)->from(‘membership’); $this->db->where(‘username’, $username); $this->db->where(‘password’, MD5($password)); Also, there is a bug in your model for checking if a user is valid. If number of rows returned from DB is 1, then the user is valid, otherwise not. … Read more
The difference in execution time would be hard to measure, as string interpolation and an implode call is going to be orders of magnitude faster than the round-trip time to the database server. We’re talking nanoseconds versus milliseconds. You’re asking the wrong question, though. It’s a really bad practice to be writing out literal SQL … Read more
