I am sorry but scanf does not work that way. To write the value the user types in at the prompt, as n[i], scanf needs an address (in memory). C is in this regard intentionally rudimentary, more so than a language like Python or JavaScript. The way you wrote your code, you end up passing … Read more
Write an algorithm accepts a positive integer n as input, when executed, prints out a list of all self-aware arrays of length n solved Write an algorithm accepts a positive integer n as input, when executed, prints out a list of all self-aware arrays of length n

If you want a char variable, use a char variable, don’t use a char array. Change char i[] = pop(); to char i = pop(); and likewise. That said, atoi() won’t be relevant there. If you want the result to be of type int, simply use an int variable. solved I want to convert a … Read more
Use sort() on each array within the array. foreach ($arr as $key=>$val) { if (is_array($val)) { sort($arr[$key]); } } See demo 1 solved sort numerical array inside associative array php

As per Sebastian’s comment: your requestCount is almost certainly a string instead of a number: new Array(4).fill() // Array(4) [ undefined, undefined, undefined, undefined ] new Array(“4”).fill() // Array(1) [ undefined ] In fact the second constructor does something wildly different from the first one. new Array(int) will create an Array with <int> empty slots. … Read more
loop through and create for item in a: item = [] or you can use list comprehension a = [[] for item in a] if your intended output is [[i], [j], [k]] then use a = [[item] for item in a] solved Is there a way to declare all the values in the list as … Read more
Just map them per index (if they have the same length) in a simple loop. Here is a demo: a = [“Isolated-1”, “SVT_FedPortGroup”, “SVT_StoragePortGroup”, “VM Network”, “test-pg-2002”] b = [“target_Isolated-1”, “target_SVT_FedPortGroup”, “target_SVT_StoragePortGroup”, “target_VM Network”, “target_test-pg-2002”] c = { “NetworkMaps”: [] } for (var i = 0; i < a.length; i++) { c.NetworkMaps.push({ “ENVID”: null, “SourcePG”: … Read more
After 4 days of trying I found the answer myself. Thanks for the great help guys… import numpy DARK = [] a = [] stack = [] for i in range(0,3): # create 3d numpy array d = numpy.array([[1, 2], [3, 4]]) a.append(d) stack.append(numpy.array(a)) # write it into the actual variable DARK.append(numpy.array(numpy.median(stack[i], 0))) solved python2.7 … Read more
If you want to print hyphens instead of zeroes, then simply print hyphens instead of zeroes. So instead of this: System.out.print(scoreArray[x][y]); you might write this: if(scoreArray[x][y] == 0) System.out.print(“-“); else System.out.print(scoreArray[x][y]); Your question doesn’t include the code that prints the array so I can’t be more specific to your code. 1 solved Display char instead … Read more
You need to use reflection. Here’s a sample: static void Main(string[] args) { string obj1 = “a string”; int obj2 = 12; DateTime obj3 = DateTime.Today; object[] obj_array = { obj1, obj2, obj3 }; foreach (object obj in obj_array) { //Print value Console.WriteLine(“Value: ” + obj.ToString()); //Print property names Console.WriteLine(“Property Names:”); foreach (PropertyInfo prop in … Read more
Frankly your code has many issues, but if I understand your objective you want something like int a[] = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; // <– declare an array. int min = a[a.length – 1]; // <– set an initial min. int max = a[0]; // <– set an … Read more
I don’t think your for loop is doing what you want it to do. Like, at all. temps[i] = in.nextInt(); // This is sensible enough closest = Math.abs(temps[0]); // Every time your loop runs, the closest value to 0 is… the absolute value of the first int in the array? //System.err.println(temps[i]); if (closest > 0) … Read more
