Eight puzzle problem

The N-puzzle problem contains N tiles (N+1 including empty tiles) where the value of N can be 8, 15, 24, etc. The puzzle is divided into the square root of (N+1) rows and the square root of (N+1) columns. These problems have an initial state or configuration and a goal state or configuration. The puzzle can be solved by shifting the tiles one by one in the empty space. The objective is to place the numbers on the tiles to match the final state using the empty space. The other name for the N-puzzle problem is the sliding puzzle.

Correct answer will be upvoted else downvoted. Computer science. There is an exhibit a1,a2,… ,an of n positive integers. You should isolate it into a negligible number of ceaseless portions, to such an extent that in each section there are no two numbers (on various positions), whose item is an ideal square. Also, it is permitted to do all things considered k such activities before the division: pick a number in the exhibit and change its worth to any certain integer. However, in this form k=0, so it isn't significant. What is the base number of consistent fragments you should utilize in the event that you will make changes ideally? Input The primary line contains a solitary integer t (1≤t≤1000) — the number of experiments. The principal line of each experiment contains two integers n, k (1≤n≤2⋅105, k=0). The second line of each experiment contains n integers a1,a2,… ,an (1≤ai≤107). It's surefire that the amount of n over all experiments doesn't surpass 2⋅105.…
Long chain of friends: You are given a list of people, and statements of the form “x knows y”. You are asked to find, is there a chain of k distinct people, such as x1 knows x2, x2 knows x3, and xk-1 knows xk.

(b) Let n be an integer. Show that n if the sum of the digits of n is a multiple of 3,then n is a multiple of 3. You must do so by a direct proof. For this problem youmay assume that ∀a, b ∈ Z, ∀m ∈ Z+, (a ≡ x (mod m) ∧ b ≡ y (mod m)) ⇒ ab ≡ xymod m. *Solve by direct proof*
Correct answer will be upvoted else downvoted. Computer science. Child Badawy's first words were "AND 0 SUM BIG", so he chose to take care of the accompanying issue. Given two integers n and k, count the number of varieties of length n with the end goal that: every one of its components are integers somewhere in the range of 0 and 2k−1 (comprehensive); the bitwise AND of every one of its components is 0; the amount of its components is just about as extensive as could be expected. Since the appropriate response can be exceptionally enormous, print its remaining portion when isolated by 109+7. Input The principal line contains an integer t (1≤t≤10) — the number of experiments you wanted to settle. Each experiment comprises of a line containing two integers n and k (1≤n≤105, 1≤k≤20). Output For each experiment, print the number of clusters fulfilling the conditions. Since the appropriate response can be exceptionally huge, print its leftover portion when…
