Answer : If I am interpreting this format correctly you have a binary file format with fixed-length records. Some of these records are not character data (COBOL computational fields?) So, you will have to read the records using a more low-level approach processing individual fields of each record: import java.io.*; public class Record { private byte[] kdgex = new byte[2]; // COMP private byte[] b1code = new byte[2]; // COMP private byte[] b1number = new byte[8]; // DISPLAY // other fields public void read(DataInput data) throws IOException { data.readFully(kdgex); data.readFully(b1code); data.readFully(b1number); // other fields } public void write(DataOutput out) throws IOException { out.write(kdgex); out.write(b1code); out.write(b1number); // other fields } } Here I've used byte arrays for the first three fields of the record but you could use other more suitable types where appropriate (like a short for the first field with rea...

Answer : In Python 3 this can be done in 2 steps: Convert timestring to datetime object Multiply the timestamp of the datetime object by 1000 to convert it to milliseconds. For example like this: from datetime import datetime dt_obj = datetime.strptime('20.12.2016 09:38:42,76', '%d.%m.%Y %H:%M:%S,%f') millisec = dt_obj.timestamp() * 1000 print(millisec) Output: 1482223122760.0 strptime accepts your timestring and a format string as input. The timestring (first argument) specifies what you actually want to convert to a datetime object. The format string (second argument) specifies the actual format of the string that you have passed. Here is the explanation of the format specifiers from the official documentation: %d - Day of the month as a zero-padded decimal number. %m - Month as a zero-padded decimal number. %Y - Year with century as a decimal number %H - Hour (24-hour clock) as a zero-padded decimal number. %M - Minute as a ze...

Answer : Use the builtin zip function. It's exactly what you want. From the python manuals: >>> x = [1, 2, 3] >>> y = [4, 5, 6] >>> zipped = zip(x, y) >>> zipped [(1, 4), (2, 5), (3, 6)] Or if you want a list of lists, instead of a list of tuples, you use zip with a list comprehension: >>> zipped = [list(t) for t in zip(x, y)] >>> zipped [[1, 4], [2, 5], [3, 6]] Try: listone = [1,2,3] listtwo = [4,5,6] merged = map(list, zip(listone, listtwo)) zip(listone, listtwo) will return a list of tuples. Since you want a list of lists you need to convert each tuple to a list. map(list, list_of_tuples) call will do exactly that.

Example: what is time complexity of insertion sort Time Complexity is : If the inversion count is O ( n ) , then the time complexity of insertion sort is O ( n ) . Some Facts about insertion sort : 1. Simple implementation : Jon Bentley shows a three - line C version , and a five - line optimized version [ 1 ] 2. Efficient for ( quite ) small data sets , much like other quadratic sorting algorithms 3. More efficient in practice than most other simple quadratic ( i . e . , O ( n2 ) ) algorithms such as selection sort or bubble sort 4. Adaptive , i . e . , efficient for data sets that are already substantially sorted : the time complexity is O ( kn ) when each element in the input is no more than k places away from its sorted position 5. Stable ; i . e . , does not change the relative order of elements with equal keys 6. In - place ; i . e . , only requires a constant amount O ( 1 ) of additional memory space Online ; i . e . , can sort a list a...

Answer : For a FlowLayoutPanel, you don't need to specify a .Location since the controls are arranged for you: Represents a panel that dynamically lays out its contents horizontally or vertically. ... The FlowLayoutPanel control arranges its contents in a horizontal or vertical flow direction. Its contents can be wrapped from one row to the next, or from one column to the next. Just change " flowLayoutPanel1 " to the name of your FlowLayoutPanel : for (int i = 0; i < 5; i++) { Button button = new Button(); button.Tag = i; flowLayoutPanel1.Controls.Add(button); }

Example: how to set a range for public int or float unity using UnityEngine ; public class Example : MonoBehaviour { // This integer will be shown as a slider, // with the range of 1 to 6 in the Inspector [ Range ( 1 , 6 ) ] public int integerRange ; // This float will be shown as a slider, // with the range of 0.2f to 0.8f in the Inspector [ Range ( 0.2f , 0.8f ) ] public float floatRange ; }

Answer : Because the operation does not need to consume the vector¹, I think it should not consume it. That only leads to extra copying somewhere else in the program: use std::collections::HashSet; use std::iter::FromIterator; fn hashset(data: &[u8]) -> HashSet<u8> { HashSet::from_iter(data.iter().cloned()) } Call it like hashset(&v) where v is a Vec<u8> or other thing that coerces to a slice. There are of course more ways to write this, to be generic and all that, but this answer sticks to just introducing the thing I wanted to focus on. ¹This is based on that the element type u8 is Copy , i.e. it does not have ownership semantics. The following should work nicely; it fulfills your requirements: use std::collections::HashSet; use std::iter::FromIterator; fn vec_to_set(vec: Vec<u8>) -> HashSet<u8> { HashSet::from_iter(vec) } from_iter() works on types implementing IntoIterator , so a Vec argument is sufficient. Ad...
