There is an endless 2-dimensional framework. The robot remains in cell (0,0) and needs to arrive at cell (x,y). Here is a rundown of potential orders the robot can execute: move north from cell (i,j) to (i,j+1); move east from cell (i,j) to (i+1,j); move south from cell (i,j) to (i,j−1); move west from cell (i,j) to (i−1,j); stay in cell (i,j). The robot needs to arrive at cell (x,y) in as couple of orders as could really be expected. In any case, he can't execute a similar order at least twice in succession. What is the base number of orders needed to reach (x,y) from (0,0)? Input The main line contains a solitary integer t (1≤t≤100) — the number of testcases. Every one of the following t lines contains two integers x and y (0≤x,y≤104) — the objective directions of the robot. Output For each testcase print a solitary integer — the base number of orders needed for the robot to…Do you see yourself using email in the not-too-distant future? The path of an email message starts with the sender and concludes with the receiver of the message. Take careful notes on everything you discover. Is there a rationale to the differences, and if so, what are they? Consider the possibility that there exist several models, each of which has a unique level of complexity (or abstraction).

Your felines like to rest and furthermore like this load of spots, so they change snoozing spot every hour consistently: Feline A progressions its snoozing place all together: n,n−1,n−2,… ,3,2,1,n,n−1,… at the end of the day, at the main hour it's on the spot n and afterward goes in diminishing request consistently; Feline B changes its resting place all together: 1,2,3,… ,n−1,n,1,2,… all in all, at the primary hour it's on the spot 1 and afterward goes in expanding request consistently. The feline B is a lot more youthful, so they have a severe pecking order: An and B don't lie together. All in all, on the off chance that both cats'd prefer to go in spot x, the A has this spot and B moves to the following submit in its request (assuming x<n, to x+1, however on the off chance that x=n, to 1).

- On a chess board of r rows and c columns there is a lone white rook surrounded by a group of opponent's black knights. Each knight attacks 8 squares as in a typical chess game, which are shown in the figure - the knight on the red square attacks the 8 squares with a red dot. The rook can move horizontally and vertically by any number of squares. The rook can safely pass through an empty square that is attacked by a knight, but it must move to a square that is not attacked by any knight. The rook cannot jump over a knight while moving. If the rook moves to a square that contains a knight, it may capture it and remove it from the board. The black knights. never move. Can the rook eventually safely move to the designated target square? The figure illustrates how the white rook can move to the blue target square at the top-right corner in the first sample case. The rook captures one black knight at the bottom-right of the board on its way.

Therefore, Einstein is a poet. All lions are animals. Some lions have manes.Therefore, some animals have manes. All booms (B) are zooms (Z). All feeps (F) are meeps (M). No boom is a feep. Therefore, no zoom is a meep.Given below are some facts and predicates for some knowledge base (KB). State if the unification for either variable x or y is possible or not. If the unification is possible then show the unified values for variables x and y. a. American (Bob), American (y) b. Enemy (Nono, America), Enemy(x,y) c.

You need to track down the number of sets of positive integers (a,b) with the end goal that balance c⋅lcm(a,b)−d⋅gcd(a,b)=x holds. Where lcm(a,b) is the most un-normal various of an and b and gcd(a,b) is the best normal divisor of an and b. Input The primary line contains one integer t (1≤t≤104) — the number of experiments. Each experiment comprises of one line containing three integer c, d and x (1≤c,d,x≤107). Output For each experiment, print one integer — the number of sets (a,b) to such an extent that the above uniformity holds.Correct answer will be upvoted else downvoted. Computer science. You are given a grid a comprising of positive integers. It has n lines and m segments. Develop a framework b comprising of positive integers. It ought to have a similar size as a, and the accompanying conditions ought to be met: 1≤bi,j≤106; bi,j is a various of ai,j; the outright worth of the contrast between numbers in any nearby pair of cells (two cells that share a similar side) in b is equivalent to k4 for some integer k≥1 (k isn't really something similar for all sets, it is own for each pair). We can show that the appropriate response consistently exists. Input The primary line contains two integers n and m (2≤n,m≤500). Every one of the accompanying n lines contains m integers. The j-th integer in the I-th line is ai,j (1≤ai,j≤16). Output The output ought to contain n lines each containing m integers.

Computer science. one maneuver, the robot should move one cell to the left or right, given that it doesn't move beyond the field of play. 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…
