 // =============> write your explanation here
+// The output is the way it is because the 'getLastDigit' function is not using the input parameter to calculate the last digit. Instead, it is always converting the global variable 'num' (which is set to 103) to a string and slicing the last character, which results in '3'. To fix this issue, we need to modify the 'getLastDigit' function to accept a parameter and use that parameter instead of the global variable 'num'. For example:
 // Finally, correct the code to fix the problem
 // =============> write your new code here
+function getLastDigit(number) {
+  return number.toString().slice(-1);
+}
+console.log(`The last digit of 42 is ${getLastDigit(42)}`);
