Write a static method called bothStart that allows the user to input two Strings and returns the String that is the longest subs

marishachu [46]

Answer:

public static String bothStart(String text1, String text2){
String s = "";
if(text1.length() > text2.length()) {
for (int i = 0; i < text2.length(); i++) {
if (text1.charAt(i) == text2.charAt(i)) {
s += text1.charAt(i);
}else{
break;
}
}
return s;
}else{
for (int i = 0; i < text1.length(); i++) {
if (text1.charAt(i) == text2.charAt(i)) {
s += text1.charAt(i);
}else{
break;
}
}
return s;
}
}

Explanation:

Let's start with creating a static method bothStart() with two String type parameters, text1 & text2 (Line 1).

Create a String type variable, s, which will hold the value of the longest substring that both inputs start with the same character (Line 2).

There are two possible situation here: either text1 longer than text2 or vice versa. Hence, we need to create if-else statements to handle these two position conditions (Line 4 & Line 13).

If the length of text1 is longer than text2, the for-loop should only traverse both of strings up to the length of the text2 (Line 5). Within the for-loop, we can use charAt() method to extract individual character from the text1 & text2 and compare with each other (Line 15). If they are matched, the character should be joined with the string s (Line 16). If not, break the loop.

The program logic from (Line 14 - 20) is similar to the code segment above (Line 4 -12) except for-loop traverse up to the length of text1 .

At the end, return the s as output (Line 21).

3-Write a Python program that has subprograms nested four deep and in which each nested subprogram references local variables, v

vivado [14]

Answer:

Explanation:

Below is a little explanation to guide us through;

There are 4 nested methods : level 0, level 1, level 2, and level 3.

Before the methods, there's a global variable defined that can be accessed by all the methods.

Level 0:

This method uses global variable, creates a level 0 variable in its scope, this level 0 variable can be used by all underlying nested methods.

Level 1: this method uses global, level 0, and level 1 variable, which can be accessed by all underlying nested methods: level 2, level 3.

Level 2: similar to te previous ones, it also uses global, level 0, level 1 variables. And creates a level 2 variable that can be accessed by level 3 also.

Level 3:

This method uses all previously created variables, and creates a new level 3 variable.

Function calls:

As you can see, the function calls are part of the method scopes. So, in order to call level 3, we need to access level 2 (because it is getting called from level 2 scope), for level 2, we must call level 1, for which level 0 needs to be called.

So, level 0 is called, which gives its out put and calls level 1, which gives its own output and calls level 2 and so on till level 3 is also called.

CODE:

global_var = "global" #accessible to all functions

def level0():

level0_var = "level 0" #accessible to level 0,1,2,3

print();

print("Level 0 function:")

print("global variable: ",global_var)

print("local variable 0: ",level0_var)

def level1():

print();

print("Level 1 function:")

level1_var = "level 1" ##accessible to level 1,2,3

print("global variable: ",global_var)

print("local variable 0: ",level0_var)

print("local variable 1: ",level1_var)

def level2():

print();

print("Level 2 function:")

level2_var = "level 2" #accessible to level 2,3

print("global variable: ",global_var)

print("local variable 0: ",level0_var)

print("local variable 1: ",level1_var)

print("local variable 2: ",level2_var)

def level3():

print();

print("Level 3 function:")

level3_var = "level 3" #accessible to level 3

print("global variable: ",global_var)

print("local variable 0: ",level0_var)

print("local variable 1: ",level1_var)

print("local variable 2: ",level2_var)

print("local variable 3: ",level3_var)

level3()

level2()

level1()

level0()

attached is the result of the code, also take note of the indentations too

cheers i hope this helps!!!!!

Which of the following is not a method of the history object?

Volgvan

Answer:

replace()

Explanation:

The history object in javascript corresponds to browsing history.

It has the following methods for navigating through the history list:

back(): Go back in the history list

forward(): Go forward in the history list

go() : Navigate to the currently pointed url in the history list. It takes a parameter which can either be a numeric index or a string which is matched with the history list content.

replace() is not a method in the history object.
