Yet Another Coin Problem

There are n𝑛 coins on the table forming a circle, and each coin is either facing up or facing down. Alice and Bob take turns to play the following game, and Alice goes first.In each operation, the player chooses a facing-up coin, removes the coin, and flips the two coins that are adjacent to it. If there are only two coins left, then one will be removed and the other won't be flipped (as it would be flipped twice). If there is only one coin left, no coins will be flipped. If there are no facing-up coins, the player loses.Decide who will win the game if they both play optimally. It can be proved that the game will end in a finite number of operations, and one of them will win.InputEach test contains multiple test cases. The first line contains the number of test cases t𝑡 (1≤t≤1001≤𝑡≤100). The description of the test cases follows.The first line of each test case contains only one positive integer n𝑛 (1≤n≤1001≤𝑛≤100), representing the number of the coins.A string s𝑠 of length n𝑛 follows on the second line of each test case, containing only "U" and "D", representing that each coin is facing up or facing down.OutputFor each test case, print "YES" if Alice will win the game, and "NO" otherwise.You can output the answer in any case (upper or lower). For example, the strings "yEs", "yes", "Yes", and "YES" will be recognized as positive responses.ExampleinputCopy35UUDUD5UDDUD2UUoutputCopyYESNONO

Two coins are tossed, the probability of getting at least one head isans.

John throws 150 coins onto a table. 60 of them show „head“, the others show „tail“. He wants the same amountof coins to show „head“ as „tail“. How many coins that show „head“ does he have to turn over?(A) 10 (B) 15 (C) 20 (D) 25 (E) 30

Bob has n coins in his pocket. One is two-headed, the rest are fair. A coin ispicked at random, lipped, and shows heads. Find the probability that the coinis two-headed

Pranav is playing a coin game with his friends. Create a simple program to assist Pranav in converting a given amount of cash into the minimum number of coins. Prompt Pranav to input the cash amount and utilize assignment operators to calculate and display the minimum number of coins needed for denominations of 100, 50, 10, 5, 2, and 1. Assume these denominations as coins with values of 100, 50, 10, 5, 2, and 1, respectively
