- You have a mixed pile of N nuts and N bolts and need to quickly find the corresponding pairs of nuts and bolts. Each nut matches exactly one bolt, and each bolt matches exactly one nut. By fitting a nut and bolt together, you can see which is bigger, but it is not possible to directly compare two nuts or two bolts. Give an efficient method for solving the problem.You are given a 2 by n grid, where the cell on row i column j contains a non-negative number ai,j . You can start at either cell in the lefttmost column, and your goal is to reach either cell in the rightmost column by a sequence of moves. You can move to an adjacent cell (if it exists) in each of the 4 cardinal directions (up,down, left and right). A path achieves a score equal to the sum of values in its cells. Note that a cell which is used twice in a path only counts its value once to the score of that path.Design an algorithm which runs in O(n) time and finds a path of minimum score from the leftmost column to the rightmost column.This problem is taken from the delightful book "Problems for Mathematicians, Young and Old" by Paul R. Halmos. Suppose that 931 tennis players want to play an elimination tournament. That means: they pair up, at random, for each round; if the number of players before the round begins is odd, one of them, chosen at random, sits out that round. The winners of each round, and the odd one who sat it out (if there was an odd one), play in the next round, till, finally, there is only one winner, the champion. What is the total number of matches to be played altogether, in all the rounds of the tournament? Your answer: Hint: This is much simpler than you think. When you see the answer you will say "of course".

We can redeem six coupons for onechocolate bar from the machine. This means that once you have startedbuying chocolate bars from the machine, you always have some coupons.We would like to know how many chocolate bars can be eaten if we startwith N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars afterpurchasing 6 bars giving us 6 coupons and then redeeming the 6 couponsfor one bar. This would leave us with one extra coupon. For 11 dollars, wecould have consumed 13 chocolate bars and still have one coupon left.For 12 dollars, we could have consumed 14 chocolate bars and have twocoupons left.Correct answer will upvoted else downvoted Petya found out with regards to another game "Kill the Dragon". As the name recommends, the player should battle with mythical beasts. To overcome a mythical serpent, you need to kill it and shield your palace. To do this, the player has a crew of n legends, the strength of the I-th saint is equivalent to man-made intelligence. As per the principles of the game, precisely one saint should go kill the mythical serpent, all the others will shield the palace. On the off chance that the mythical serpent's protection is equivalent to x, you need to send a saint with a strength of essentially x to kill it. Assuming the winged serpent's assault power is y, the absolute strength of the saints protecting the palace ought to be ssentially y. The player can build the strength of any legend by 1 for one gold coin. This activity should be possible quite a few times. There are m winged serpents in the game, the I-th of them has protection equivalent to…
- Let L be a line in the xy plane. If L is a vertical line, its equation is x=afor some real number a. Suppose L is not a vertical line and its slope is m. Then the equation of L is y=mx + b, where b is the y-intercept. If L passes through the point (x0,y0), the equation of L can be written as y –y0=m(x –x0). If (x1,y1)and (x2,y2)are two points in the xy plane and x1≠x2, the slope of the line passing through these points is m = (y2-y1)/ (x2-x1). Write a program that prompts the user to enter two points in the xy plane. The program outputs the equation of theline and uses ifstatements to determine and output whether the line is vertical, horizontal, increasing, or decreasing. If L is a nonvertical line, output its equation in the form y=mx + b.You have a mixed pile of N nuts and N bolts and need to quickly find the corresponding pairs of nuts and bolts.

- There are four people who want to cross a rickety bridge; they all begin on the same side. You have 17 minutes to get them all across to the other side. It is night, and they have one flashlight. A maximum of two people can cross the bridge at one time. Any party that crosses, either one or two people, must have the flashlight with them. The flashlight must be walked back and forth; it cannot be thrown, for example. Person 1 takes 1 minute to cross the bridge, person 2 takes 2 minutes, person 3 takes 5 minutes, and person 4 takes 10 minutes. A pair must walk together at the rate of the slower person's pace. Write the specification of an algorithm that solves the problem.Mr. Naughty loves to play with balls. So, his friend, Mr. Nice, gave him n balls to play the game. Each ball has exactly two numbers (more number and number below). In one move Mr. Naughty can rotate any ball that its bottom is now rising. Mr. Nice knows a small amount of this movements that can make at least half of the balls show the same number at the top. So, in order to win Mr Nice's game, Mr. Naughty has to earn a small amount of it it goes. It is not always possible to make such movements that satisfy what is provided in this case Mr. Naughty should see that it is "Impossible" to make such movements. Help Mr. Naughty win the game using C programming language. Input 3 3 100 100 3 54 Output 1Although the plot function is designed primarily for plotting standard xy graphs, it can be adapted for other kinds of plotting as well. b. Make a plot of the curve, which is defined parametrically by the equations x = 2cosθ + cos2θ, y = 2sinθ - sin2θ, where 0 < θ < 2π. Take a set of values of θ between zero and 2π and calculate x and y for each from the equations above, then plot y as a function of x. b. Taking this approach a step further, one can make a polar plot r = f(θ) for some function f by calculating r for a range of values of θ and then converting r and θ to Cartesian coordinates using the standard equations x = r cosθ, y = r sinθ. Use this method to make a plot of the function r = ecosθ – 2 cos(4θ) + sin5 (θ/12) in the range 0 <= θ <= 24π. use python code to answer the highlight one
