Alexa has two stacks of non-negative integers, stack A and stack B where index 0 denotes the top of the stack. here we just reverse the array by first print the array last index than second last index like n, n-1, n-2,..... up to (greater or equal) 0 (Zero), Each plate has a number written on it. Following are the key points to note in the problem statement: 1) A box can be placed on top of another box only if both width and depth of the upper placed box are smaller than width and depth of the lower box respectively. In the end, I had to implement a Python 3 solution (with the same logic), which passed all the test cases, to solve these problems. You need to create a new vertical pile of cubes.

If you join KK adjacent buildings, they will form a solid rectangle of area K×min(hi,hi+1,…,hi+k−1)K×min(hi,hi+1,…,hi+k−1). You can change the height of a stack by removing and discarding its topmost cylinder any number of times. Solutions to HackerRank problems. The majority of the solutions are in Python 2. You start picking up the plates from the top one by one and check whether the number written on the plate is divisible by a prime…. Ask Question Asked today. Each building has a height given by hi,i∈[1,N]hi,i∈[1,N]. A stable tower of height n is a tower consisting of exactly n tiles of unit height stacked vertically in such a way, that no bigger tile is placed on a smaller tile. You have three stacks of cylinders where each cylinder has the same diameter, but they may vary in height. An example is shown below : We have infinite number of tiles of sizes 1, 2, …, m. The task is calculate the number of different stable tower of height n that can be built from these tiles, with a restriction … The problem is quite straight forward.
