"Given a binary tree, locate the optimum path amount. "We can rotate numbers by 180 levels to create brand-new numbers.

When 2, 3, 4, 5, and 7 are revolved 180 levels, they come to be void. A complex number is a number that when rotated 180 degrees ends up being a different number with each number valid.(Note that the rotated number can be greater than the original number.) Provided a favorable integer N, return the variety of complex numbers in between 1 and N comprehensive." (Solution) "Provided 2 words (beginWord and endWord), and a thesaurus's word list, discover the size of quickest transformation sequence from beginWord to endWord, such that: 1) Only one letter can be changed at once and, 2) Each changed word needs to exist in the word list." (Solution) "Given a matrix of N rows and M columns.

When it attempts to move right into a blocked cell, its bumper sensing unit discovers the barrier and it remains on the present cell.

(A domino is a ceramic tile with two numbers from 1 to 6 - one on each half of the tile.) We might turn the i-th domino, to make sure that A [i] and B [i] swap values. Return the minimal number of turnings to make sure that all the worths in A coincide, or all the values in B coincide.

Sometimes, when keying a personality c, the key may obtain long pushed, and the character will be entered 1 or even more times. You check out the typed personalities of the key-board. Return True if it is possible that it was your friends name, with some characters (potentially none) being long pressed." (Option) "Provided a string S and a string T, discover the minimum window in S which will certainly consist of all the personalities in T in complexity O(n)." (Service) "Given a checklist of query words, return the number of words that are stretchy." Note: see web link for more information.

If there are numerous such minimum-length home windows, return the one with the left-most beginning index." (Solution) "A strobogrammatic number is a number that looks the very same when revolved 180 degrees (took a look at upside-down). Locate all strobogrammatic numbers that are of size = n." (Solution) "Provided a binary tree, find the length of the lengthiest course where each node in the path has the very same worth.
