1 coin flip There is a row of coins on the desktop, N in total, each coin is positive up. Now I want to flip all the coins to the opposite side up, the rule is to flip any N-1 each time (the front is turned to the opposite side up, and vice versa ). Find a shortest operation

answer.InputMultiple sets of inputs, two positive integers per line n m, where n, M OutputOutputs a positive integer that indicates how many coins are at the beginning of the opposite direction.Sample input2 3Sample output1first consider a one-dimensional situation, if the number of x is reversed odd number of times, then its approximate number must be odd, and only the number of squares is an odd number, then that is, for one-dimensional case only X is the square number when it is flipped odd

Problem descriptionXiao Ming first put the coin into a matrix of n rows M column. Xiao Ming then performed a Q operation on each coin separately. The definition of the Q operation for the coin in row y of line x: Turn all the coins in line i*x, section j*y. Where I and J are arbitrary to make the operation feasible positive integer, line number and column number

Problem descriptionXiao Ming is playing a "coin-flipping" game.There are a number of coins lined up on the table. We use * to denote the positive side, and O for the opposite side (lowercase letters, not 0).For example, the possible scenario is: **oo***ooooIf you flip the two coins on the left at the same time, change to: oooo***ooooNow Xiao Ming's question is: if you know the initial state and to achieve t

Daily Punch-In (1/1) Portal: Click to open link The main idea: a n*m matrix flip coin, turn a coin will involve around four, ask all the coins face up to the minimum need to turn over which few coins. Ideas: It is not the same as how many times the previous question asked, this time to record the status. First, we first think of enumerating the first row, and th

You is given the number of rows and number of n_rows columns of n_cols a 2D binary matrix where all values is initially 0.Write a function flip which chooses a 0 value uniformly at random, changes it to 1, and then returns the position [row.id, col.id] of that value.Also, write a function reset which sets all values 0. Try to minimize the number of calls to System ' s math.random () and optimize the time an
