Write a JAVA program of A Data File Structure for a connected graph that produces a tree. There is a cycle in a graph only if there is a back edge present in the graph. A back edge is an edge that is joining a node to itself (self-loop) or one of its ancestor in the tree produced by Data File Structure. To find the back edge to any of its ancestor keep a visited array and if there is a back edge to any visited node then there is a loop and return true. Algorithm: 1. Create the graph using the given number of edges and vertices. 2. Create a recursive function that that current index or vertex, visited and recursion stack. 3. Mark the current node as visited and also mark the index in recursion stack. 4. Find all the vertices which are not visited and are adjacent to the current node. Recursively call the function for those vertices, if the recursive function returns true return true. 5. If the adjacent vertices are already marked in the recursion stack then return true. 6. Create a wrapper class, that calls the recursive function for all the vertices and if any function returns true, return true. 7. Else if for all vertices the function returns false return false. 1 2 Adja cent list (g) 0-1,2,3 1-0, 2 2-0,1 3- 0,4 4 → 3 3 v[ 0 ] is already visited and *i= parent isCyclicUtil( 0,-1), vis[ 0 ] = true isCyclicUtil(1,0), vis[ 1 ] = true 2 iscyclicutil(2,1), vis[2] = true v[ 0 ] is already visited and *i!= parent cycle found

12. Solar System. In Python,use a Canvas widget to draw each of the planets of our solar system. Draw the sun first, then each planet according to distance from the sun (Mercury, Venus, Earth, Mars, Jupiter Saturn, Uranus, Neptune, and the dwarf planet, Pluto). Label each planet using the create_text method.

Complete the code with if statement(s) to solve this problem? Print the message "charge your phone" if you have a charger and battery level is 15% or less. Print "Charge your phone when your charger s is available." if the battery is 15% or less and you don't have a charger. Print "Your battery is charged" if the battery level is more than 15%. Please set the font in the text editor to Courier New to make it easier for code to line up. 1 charger_available = True 2 battery_level = 0.15 3 4 7 10 Charge your phone.

Is it so, or am I wrong? The Text element of a newly generated form initially contains the name of the form. This is done at the beginning of the setup process.

simply fill in the blanks. To make it easier for you to enter the number, you may simply enter the number without having to indicate the base using the subscript. For example, you may enter AF instead of AFsixteen: Fill in the blanks. Provide the number immediately before and after the given number in the given base, respectively. No work to be shown for this problem. You may Click on Show Rich-Text Editor option for more formatting tools, such as subscript. 8D9FFsixteen. 1. F8DAOsixteen, 2. 3. 57100eight 4. , 100110000two, 4200seven, 5.

Using square braces. In the previous question you had used the dot notation to add key values in an object  and in this you have to add squares braces and print the object before and after adding

Can you please answer the following question? The program is JavaScript and needs to look exactly like the example attached. Thanks!

Please fix these in the above splution, it is not fully correct. "You're invited" needs to be formatted correctly. With a larger font, using BS classes only. Use Bootstrap classes to make a circular image with a border - around the image only. "Don't tell the cats" color should be set with BS classes.

Counting the growth rings of a tree is a good way to tell the age of a tree. Each growth ring counts as one year. Use a Canvas widget to draw how the growth rings of a 5-year-old tree might look. Then, using the create_text method, number each growth ring starting from the center and working outward with the age in years associated with that ring.

Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used…
