681 "Question Description": "Problems in Computer Science are often classified as belonging to a certain class of problems (e.g., NP, Unsolvable, Recursive). In this problem you will be analyzing a property of an algorithm whose classification is not known for all possible inputs.\n Consider the following algorithm:\n 1. input n\n 2. print n\n 3. if n = 1 then STOP\n 4. if n is odd then n ← 3n + 1\n 5. else n ← n/2\n 6. GOTO 2\nGiven the input 22, the following sequence of numbers will be printed:22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1\nIt is conjectured that the algorithm above will terminate (when a 1 is printed) for any integral input value. Despite the simplicity of the algorithm, it is unknown whether this conjecture is true. It has been verified, however, for all integers n such that 0 < n < 1, 000, 000 (and, in fact, for many more numbers than this.)\nGiven an input n, it is possible to determine the number of numbers printed before and including the 1 is printed. For a given n this is called the cycle-length of n. In the example above, the cycle length of 22 is 16.\nFor any two numbers i and j you are to determine the maximum cycle length over all numbers between and including both i and j.\n",
682 "Input Requirements": "The input will consist of a series of pairs of integers i and j, one pair of integers per line. All integers will be less than 10,000 and greater than 0.

You can assume that no operation overflows a 32-bit integer.\n",
683 "Output Requirements": "For each pair of input integers i and j you should output i, j, and the maximum cycle length for integers between and including i and j. These three numbers should be separated by at least one space with all three numbers on one line and with one line of output for each line of input.

A robot *instruction* is a string of the letters 'L', 'R', and 'F' which represent, respectively, the instructions:\n\n- *Left*: the robot turns left 90 degrees and remains on the current grid point.\n- *Right*: the robot turns right 90 degrees and remains on the current grid point.\n- *Forward*: the robot moves forward one grid point in the direction of the current orientation and maintains the same orientation.\n\nThe direction *North* corresponds to the direction from grid point (x,y) to grid point (x,y+1).\n\nSince the grid is rectangular and bounded, a robot that moves \"off\" an edge of the grid is lost forever.

1164 "Question Description": "Robotics, robot motion planning, and machine learning are areas that cross the boundaries of many of the subdisciplines that comprise Computer Science: artificial intelligence, algorithms and complexity, electrical and mechanical engineering to name a few. In addition, robots as \"turtles\" (inspired by work by Papert, Abelson, and diSessa) and as \"beeper-pickers\" (inspired by work by Pattis) have been studied and used by students as an introduction to programming for many years.\n\nThis problem involves determining the position of a robot exploring a pre-Columbian flat world.\n\nGiven the dimensions of a rectangular grid and a sequence of robot positions and instructions, you are to write a program that determines for each sequence of robot positions and instructions the final position of the robot.\n\nA robot *position* consists of a grid coordinate (a pair of integers: x-coordinate followed by y-coordinate) and an orientation (N,S,E,W for north, south, east, and west). A robot *instruction* is a string of the letters 'L', 'R', and 'F' which represent, respectively, the instructions:\n\n- *Left*: the robot turns left 90 degrees and remains on the current grid point.\n- *Right*: the robot turns right 90 degrees and remains on the current grid point.\n- *Forward*: the robot moves forward one grid point in the direction of the current orientation and maintains the same orientation.\n\nThe direction *North* corresponds to the direction from grid point (x,y) to grid point (x,y+1).\n\nSince the grid is rectangular and bounded, a robot that moves \"off\" an edge of the grid is lost forever. However, lost robots leave a robot \"scent\" that prohibits future robots from dropping off the world at the same grid point. The scent is left at the last grid position the robot occupied before disappearing over the edge. An instruction to move \"off\" the world from a grid point from which a robot has been previously lost is simply ignored by the current robot.",
1165 "Input Requirements": "The first line of input is the upper-right coordinates of the rectangular world, the lower-left coordinates are assumed to be 0,0.\n\nThe remaining input consists of a sequence of robot positions and instructions (two lines per robot). A position consists of two integers specifying the initial coordinates of the robot and an orientation (N,S,E,W), all separated by white space on one line. A robot instruction is a string of the letters 'L', 'R', and 'F' on one line.\n\nEach robot is processed sequentially, i.e., finishes executing the robot instructions before the next robot begins execution.\n\nInput is terminated by end-of-file.\n\nYou may assume that all initial robot positions are within the bounds of the specified grid. The maximum value for any coordinate is 50. All instruction strings will be less than 100 characters in length.",
1166 "Output Requirements": "For each robot position/instruction in the input, the output should indicate the final grid position and orientation of the robot. If a robot falls off the edge of the grid the word 'LOST' should be printed after the position and orientation.",
