An Euler tour of a graph is a path that traverses each edge exacty once. In the context of a tree, we say that each edge is bidirectional, so the Euler tour is the path along the tree that begins at the root and ends at the root, traversing each edge exactly twice - once to enter the subtree at the other endpoint and X once to leave iit You can think of an Euler tour as just being a depth first traversal where we return to the root at the end. In other words, Euler tour traversal of a tree is defined as a way of traversing tree such that each node is added to the tour when we visit it (either moving down from parent or returning from child). See the following example. 18 13 12 3 11 14 15 16 17 7

What is the difference of the meaning of the word ray in math and in computer science?     In both areas, the meaning is that a ray is a directed line segment.     In both areas, the meaning is that a ray is “half” of a line that has an origin and extends infinitely in one direction.     Computer science: A ray is “half” of a line that has an origin and extends infinitely in one direction.  Math:  A ray is a directed line segment.     Computer science: A ray is a directed line segment. Math: A ray is “half” of a line that has

Q.  Given a 2d grid map of '1's (land) and '0's (water),count the number of islands.An island is surrounded by water and is formed byconnecting adjacent lands horizontally or vertically.You may assume all four edges of the grid are all surrounded by water. Example 1: 11110110101100000000Answer: 1 Example 2: 11000110000010000011Answer: 3""" def num_islands(grid):    count = 0    for i in range(len(grid)):        for j, col in enumerate(grid[i]):            if col == 1:                dfs(grid, i, j)                count += 1 Please code it. .

IN VISUAL BASIC, solve Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

Can you help me with this code because this is a little difficult for me:question that i need help with:The Lights Out puzzle consists of an m x n grid of lights, each of which has two states: on and off. The goal of the puzzle is to turn all the lights off, with the caveat that whenever a light is toggled, its neighbors above, below, to the left, and to the right will be toggled as well. If a light along the edge of the board is toggled, then fewer than four other lights will be affected, as the missing neighbors will beignored. In this section, you will investigate the behavior of Lights Out puzzles of various sizes by implementing a LightsOutPuzzle class task: A natural representation for this puzzle is a two-dimensional list of Boolean values, where True corresponds to the on state and False corresponds to the off state. In the LightsOutPuzzle class, write an initialization method __init__(self, board) that stores an input board of this form for future use. Also write a method…
