Answer:
39 + 3
42
393
Explanation:
In this line System.out.println("39 + 3"), the quotation marks are used to delimit a string, then when printed in the console the string is printed as-is.
In the next line: System.out.println(39 + 3), without the quotation marks, the 39+3 is treated as a normal addition and prints the result of the operation.
In the last line printed with the code System.out.println("39" + 3,; the symbol + is used to concatenate the string 39 with the number 3, since the string has no spaces they are printed together.
Answer:
Explanation:
The following code is written in Python. It creates a method for each one of the questions asked and then tests all three with the same test case which can be seen in the picture attached below.
def alternating_list(lst1, lst2):
lst3 = []
for x in range(len(lst1)):
lst3.append(lst1[x])
try:
lst3.append(lst2[x])
except:
pass
if len(lst2) > len(lst1):
lst3.extend(lst2[len(lst1):])
return lst3
def reverse_alternating(lst1, lst2):
lst3 = []
if len(lst1) == len(lst2):
for x in range(len(lst1) - 1, -1, -1):
lst3.append(lst1[x])
lst3.append(lst2[x])
return lst3
def alternating_list_no_extra(lst1, lst2):
lst3 = []
max = 0
if len(lst1) > len(lst2):
max = len(lst2)
else:
max = len(lst1)
for x in range(max):
lst3.append(lst1[x])
try:
lst3.append(lst2[x])
except:
pass
return lst3
Answer:
1. C) Embedded Style
