Sample Solution: Python Code: importnumpyasnp# Import NumPy library# Create two regular NumPy arrays with some valuesdata1=np.array([1,2,np.nan,4,5])data2=np.array([5,np.nan,2,3,1])# Create masks to specify which values to mask (e.g., NaN values)mask1=np.isnan(data1)mask2=...
Code 2: firstList=(1,2,9,8,99,89)secondList=(14,24,56,38,97,11)result=[x+yforx,yinzip(firstList,secondList)]print(result) Output: [15, 26, 65, 46, 196, 100] In this code, we initialize two lists,firstListandsecondList, each containing numerical elements. Next, thezip()funct...

Der obige Code nimmt zwei Eingaben der Binärzahlen und addiert sie. Siehe die Ausgabe: Please enter the first binary number: 1010101Please enter the second binary number: 111111The result for addition is: 10010100
In this tutorial, we will learn about the binary-coded decimal (BCD code) and its addition (binary-coded decimal addition) with the help of examples.
