As such, if the robot was in the cell I, it should move to either the cell i−1 or the cell i+1, as long as it lies among 1 and n (endpoints comprehensive). The cells, in the request they are visited (counting the cell the robot is set), together make a decent way. Every cell I has a worth computer based intelligence related with it. Let c0,c1,… ,ck be the succession of cells in a decent way in the request they are visited (c0 is the cell robot is at first positioned, c1 is the cell where the robot is after its first move, etc; all the more officially, ci is the cell that the robot is at after I moves). Then, at that point, the worth of the way is determined as ac0+ac1+⋯+ack. Your errand is to work out the amount of qualities over all conceivable great ways. Since this number can be…
In "Computing Machines and Intelligence," the English mathematician Alan Turing (1912-1954) wrote, "If each man had a definite set of rules of conduct by which he regulated his life, he would be a machine, but there are no such rules, so men cannot be machines." Using what you now know about Logic, determine whether this statement make sense and explain. Construct a truth table for Turing's statement and determine if this statement is a tautology.

You have n particular focuses (x1,y1),… ,(xn,yn) on the plane and a non-negative integer boundary k. Each point is a tiny steel ball and k is the draw in force of a ball when it's charged. The draw in power is something very similar for all balls. In one activity, you can choose a ball I to charge it. When charged, all balls with Manhattan distance all things considered k from ball I move to the situation of ball I. Many balls may have a similar facilitate after an activity. All the more officially, for all balls j with the end goal that |xi−xj|+|yi−yj|≤k, we dole out xj:=xi and yj:=yi. An illustration of an activity. Subsequent to charging the ball in the middle, two different balls move to its position. On the right side, the red dab in the middle is the normal situation of those balls. Your errand is to observe the base number of activities to move all balls to a similar…

However, Sasha comprehends that enchanted squares have as of now been examined by many individuals, so he sees no feeling of concentrating on them further. All things considered, he designed his own kind of square — a superb square. A square of size n×n is called prime if the accompanying three conditions are held all the while: all numbers on the square are non-negative integers not surpassing 105; there are no indivisible numbers in the square; amounts of integers in each line and every segment are indivisible numbers. Sasha has an integer n. He requests you to view as any great square from size n×n. Sasha is certain beyond a shadow of a doubt such squares exist, so help him! Input The principal line contains a solitary integer t (1≤t≤10) — the number of experiments. Every one…

The I-th train beginning at the base end is at first at (i,0) and will be at (i,T) after T minutes, and the I-th train beginning at the left end is at first at (0,i) and will be at (T,i) after T minutes. All trains show up at their objections following 101 minutes. In any case, Gildong observed that a few trains booked to leave at a particular time, at the same time, are extremely hazardous. As of now, n trains are planned to leave from the base end and m trains are booked to withdraw from the left end. In the event that two trains are both at (x,y) simultaneously for some x and y, they will collide with one another. In this way, he is requesting you to observe the base number from trains that ought to be dropped to forestall every such accident. Input Each test contains at least one experiments.

With that impact you can pour water starting with one glass then onto the next however many occasions as you like. In any case, as a result of the glasses' abnormal shape (and absolutely disconnected to your regular awkwardness), each time you attempt to move any measure of water, a big part of the sum is spilled on the floor. Officially, assume a glass I at present contains ci units of water, and a glass j contains cj units of water. Assume you attempt to move x units from glass I to glass j (normally, x can not surpass ci). Then, at that point, x/2 units is spilled on the floor. After the exchange is done, the glass I will contain ci−x units, and the glass j will contain min(aj,cj+x/2) units (abundance water that doesn't fit in the glass is likewise spilled). Each time you move water, you can…

There are m1 sets of first courses and second courses that go poorly with one another, m2 sets of second courses and beverages, and m3 sets of beverages and pastries that turn out poorly with one another. Ivan needs to purchase precisely one first course, one second course, one beverage, and one pastry so they work out in a good way for one another, and the absolute expense of the supper is the base conceivable. Assist him with tracking down the least expensive supper choice! Input The primary line contains four integers n1, n2, n3 and n4 (1≤ni≤150000) — the number of kinds of first courses, second courses, beverages and treats, individually. Then, at that point, four lines follow. The primary line contains n1 integers a1,a2,… ,an1 (1≤ai≤108), where simulated intelligence is the expense of the I-th kind of first course. Three next lines indicate the expenses of second…
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…
