N is uninitialised meaning N could have any integer value. That unknown value is copied to M, and then scanf() called to assign a value to N. The program needs to verify that system calls (like scanf()) has done what was expected with user input. Below is a “better” version that tries to protect itself … Read more
QueryReadOnlyListAsync calls the Dapper extension method QueryAsync, which returns a Task<IEnumerable<T>>. IEnumerable doesn’t implement IReadOnlyList. You can’t return Task<IEnumerable> if the method’s return type is Task<IReadOnlyList>. You need to convert the IEnumerable into a collection that implements IReadOnlyList, such as a regular List: //Make method async so you can await the Task returned by ExecuteWithResiliency … Read more
You can sequentially loop through the string and append the inverted character to another string. You can check whether the character is lowercase or not by converting it to lowercase (with String.toLowerCase) and checking whether the result is equal to the original. let swappedName = “elZerO”; let res = “”; for (let i = 0; … Read more
This is a popular question for people who learn python. The answer is that python has no pointer but using id(). And id() return C language memory address in CPython interpreter.

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
