input
standard input
output
standard output

The king is left alone on the chessboard. In spite of this loneliness, he doesn't lose heart, because he has business of national importance. For example, he has to pay an official visit to square t. As the king is not in habit of wasting his time, he wants to get from his current position s to square t in the least number of moves. Help him to do this.

In one move the king can get to the square that has a common side or a common vertex with the square the king is currently in (generally there are 8 different squares he can move to).

Input

The first line contains the chessboard coordinates of square s, the second line \u2014 of square t.

Chessboard coordinates consist of two characters, the first one is a lowercase Latin letter (from a to h), the second one is a digit from 1 to 8.

Output

In the first line print n \u2014 minimum number of the king's moves. Then in n lines print the moves themselves. Each move is described with one of the 8: L, R, U, D, LU, LD, RU or RD.

L, R, U, D stand respectively for moves left, right, up and down (according to the picture), and 2-letter combinations stand for diagonal moves. If the answer is not unique, print any of them.

A. Shortest path of the king
time limit per test
1 second
memory limit per test
64 megabytes
input
standard input
output
standard output

The king is left alone on the chessboard. In spite of this loneliness, he doesn't lose heart, because he has business of national importance. For example, he has to pay an official visit to square t. As the king is not in habit of wasting his time, he wants to get from his current position s to square t in the least number of moves. Help him to do this.

In one move the king can get to the square that has a common side or a common vertex with the square the king is currently in (generally there are 8 different squares he can move to).

Input

The first line contains the chessboard coordinates of square s, the second line \u2014 of square t.

Chessboard coordinates consist of two characters, the first one is a lowercase Latin letter (from a to h), the second one is a digit from 1 to 8.

Output

In the first line print n \u2014 minimum number of the king's moves. Then in n lines print the moves themselves. Each move is described with one of the 8: L, R, U, D, LU, LD, RU or RD.

L, R, U, D stand respectively for moves left, right, up and down (according to the picture), and 2-letter combinations stand for diagonal moves. If the answer is not unique, print any of them.

Each group consists of exactly n students. An academic performance of each student is known \u2014 integer \nvalue between 1 and 5.\n\nThe school director wants to redistribute students between groups so that each of the two groups has the same number of students whose academic performance is equal to 1, the same \nnumber of students whose academic performance is 2 and so on. In other words, the purpose of the school director is to change the composition of groups, so that for each value of\nacademic performance the numbers of students in both groups are equal.\n\nTo achieve this, there is a plan to produce a series of exchanges of students between groups. During the single exchange the director selects one student from the class A and one \nstudent of class B. After that, they both change their groups.\n\nPrint the least number of exchanges, in order to achieve the desired equal numbers of students for each academic performance.\n\nInput\nThe first line of the input contains integer number n (1\u2009\u2264\u2009n\u2009\u2264\u2009100) \u2014 number of students in both groups.\nThe second line contains sequence of integer numbers a1,\u2009a2,\u2009...,\u2009an (1\u2009\u2264\u2009ai\u2009\u2264\u20095), where ai is academic performance of the i-th student of the group A.\nThe third line contains sequence of integer numbers b1,\u2009b2,\u2009...,\u2009bn (1\u2009\u2264\u2009bi\u2009\u2264\u20095), where bi is academic performance of the i-th student of the group B.\n\nOutput\nPrint the required minimum number of exchanges or -1, if the desired distribution of students can not be obtained.\n\nExamples\nInput\n4\n5 4 4 4\n5 5 4 5\n\nOutput\n1\n\nInput\n6\n1 1 1 1 1 1\n5 5 5 5 5

In each corner of the arena there was a special pillar, and the rope strung between the pillars marked the arena edges.\n\nRecently the scientists from Berland have discovered the remains of the ancient circus arena. They found only three pillars, the others were destroyed by the time.\n\nYou are given the coordinates of these three pillars. Find out what is the smallest area that the arena could have.\nInput\n\nThe input file consists of three lines, each of them contains a pair of numbers \u2013\u2013 coordinates of the pillar. Any coordinate doesn't exceed 1000 by absolute value, and is given with at most six digits after decimal point.\nOutput\n\nOutput the smallest possible area of the ancient arena. This number should be accurate to at least 6 digits after the decimal point. It's guaranteed that the number of angles in the optimal polygon is not larger than 100.\nSample test(s)\nInput\n\n0.000000 0.000000\n1.000000 1.000000\n0.000000 1.000000\n\nOutput\n\n1.00000000\n\n\"\"\"\n\nimport math\n\nclass Point(object):\n def __init__(self, x, y):\n self.x = x*1.0\n self.y = y*1.0\n\n def GetDistance(self, p2):\n dx = self.x -

and \n always goes back to the floor x before transposing a next passenger. \n The elevator spends one unit of electricity to move between neighboring floors. \n So moving from the a-th floor to the
