How to Randomly Remove Elements from a NumPy Array?
This tutorial will discuss about unique ways to randomly remove elements from a numpy array. Suppose we have an array of numbers, numbers = np.array([34, 35, 78, 61, 56, 71, 90, 91]) For this, we will create an array of random indices from this array of size N. Like this, Advertisements # Use the `random.choice()` …

Remove Array elements that are in Another Array – Python
This tutorial will discuss about unique ways to remove elements from array that are in another array – Python. Suppose we have two NumPy Arrays, mainArray = np.array([14, 23, 30, 41, 53]) otherArray = np.array([23, 41]) Now we want to remove only those elements from the mainArray which are present in the otherArray. Basically we …

Check if All elements are Greater than a Number in C++
This tutorial will discuss about a unique way to check if all elements are greater than a number in C++. To check if all the elements of an array are greater than a given number, we need to iterate over all the elements of array and check each element one by one. For that we …
