there is a grey cube 3x3x3 was colored into red (all of its edges) . Next it was splitted into 1x1x1 cubes. 1 of these small cubes was chosen uniformly and uniformly thrown on a table. Find the P of "You can't see any red edges on this small cube"

Suppose there is a rectangular map where you can only travel up or right to go from a start location in the bottom left corner to the top right corner, and each move is discrete. Write a program that prints all possible solutions to get from the start to finish.

phone numbers: provided a phone number (654-876-0987), return all possible strings that the phone number could represent if 2 -> {A, B, C}, 3 -> {D, E, F}, and so on common substring: find the biggest common substring in 2 strings, "abcdef" "gbcdh" would return "bcd"

Write a function to determine if a bin tree is a valid BST. I wrote a fully working solution in 3-5 minutes. It was also the most optimal but maybe because she needed to kill time, she asked me to rewrite it in what she thought was optimal (her reasoning didn't make much sense). Then she asked me for time and space requirements of the solutions. I said O(n) for both which is correct but she insisted that the space requirement was O(logn) which is wrong.
