Here you have again some things wrong. Before you create new threads with similar content, stick to one thread. In your code you also never check if malloc fails. It’s always better to do that. For simplicity I’ve omitted these checks in my suggestions. 1. Why do you do S1[0].top=-1; in makeEmpty? create already does … Read more
You can use a TreeMap to keep the items sorted by key and just increment a counter for each occurrence. import java.util.Map; import java.util.Map.Entry; import java.util.TreeMap; public class Counter { public static void main(String[] args) { int[] arr = { 2, 5, 6, 1, 2, 1, 5, 3, 6, 1, 2, 1, 5 }; Map<Integer, … Read more
Both your snippets are incorrect. You are misusing the post increment operator. if(data[counter]<data[counter++]) will never be true, just like if(data[counter]<data[counter]) will never be true. The post increment operator returns the original value of the incremented variable. It’s not clear why you are incrementing counter in the loop body anyway. You should only increment it in … Read more
The issue is here: int [] NumArray; element = NumArray.length -1 Details: you declared NumArray but never initialize it until the constructor is called (this is 100% ok) but the next line you are trying to get NumArray.length of the non initialized array and that is the reason… Solution: place this line inside the constructor, … Read more
The problem is that you input too many characters for cin >> ch;. Since m == 40, you declared it as char ch[40]. This allows you to enter 39 characters (not 40 because of the trailing ‘\0’ character), but you entered much more than that, so it wrote outside the array boundary, which results in … Read more
Loop through your array and check if the number is within the given range (min number for example is nine and max number is 30). Add it to a newly created array then return the array when you’re done. I’ll provide a code snipit shortly. public ArrayList<Integer> withinRange(int min, int max, int[]array){ ArrayList<Integer> list = … Read more
This will shift chars to the right, making room for insertion. void rshift( char *s ){ int n = strlen( s); s[ n + 1] = 0; while( n ){ s[ n ] = s[ n-1 ]; n–; } } int main(){ char *p = strchr(sentence , replace); if( p ) { p++; // insert … Read more
using combination of array_map, array_column and array_reverse : $myArrays = array( array(1, 2, 3, 4), array(5, 6, 7, 8), array(9, 10, 11, 12), array(13, 14, 15, 16) ); $index = 0; $myArrays = array_map(function ($v) use (&$index, $myArrays) { if (($index % 2) != 0) { echo implode(“\n”, array_reverse(array_column($myArrays, $index))) . “\n”; } else { … Read more
Variables and array elements are all references to objects. They are not the actual objects. To illustrate, I’ll “name” actual objects using a number scheme, e.g. #1 is the first object. Your code runs as follows: Class is initialized by the JVM, and root1, root2, and root3 are all null. Node root[]={root1,root2,root3} is executed and … Read more
You can foreach to loop through all item and call in the array like: foreach($yourArray as $item) { echo $item->label; echo $item->file; } Or you can be using json_decode to cast your object to the array. $result = json_decode($data, true); 2 solved How to echo values from this array? [duplicate]
You can loop through the array to get the maximum value and you only need to retain the largest value found thus far, so: int max = Int32.MinValue; for (var i = 0; i < array.Length; i++) { if (array[i] > max) { max = array[i]; } } Console.WriteLine(max); You can also use .Max() and … Read more
Consider this file divided in middle present two record in same format, you need to design class that contains fields that you want to get from this file. After that you need to read List<String> fileLines = Files.readAllLines(Path pathToYourFile, Charset cs); and parse this file with help of regular expressions. To simplify this task you … Read more
just use count(), $array = array(1,3,2,4,6); $a=count($array); echo $a; solved PHP : Counting how many element in an array [closed]
Edit: Okay! A switch! Let’s do it! var count = 0; for(var i = number.length; i–;){ switch(true){ case typeof number[i] == ‘number’: count++; } } alert(count); 8 solved Using a Javascript switch statement, how can I count the number of elements (numbers only) in an array? [closed]
You could use a search and test if the count is smaller then the max items and for the sum of seats. function getCombinations(array, sum, max) { function fork(i, t) { var s = t.reduce(function (r, a) { return r + a[2]; }, 0); if (s >= sum) { result.push([s, t.map(function (a) { return [a[1], … Read more
