Given an integer x, return true if x is a palindrome (read from left to right and from right to left), and false otherwise. Example: • Input: x = 121, Output: true ● Input: x = -121, Output: false

Description A mathmatician Goldbach's conjecture: any even number(larger than 2) can divide into two prime number’s sum.But some even numbers can divide into many pairs of two prime numbers’ sum. Example:10 =3+7, 10=5+5, 10 can divide into two pairs of two prime number. Input Input consist a positive even number n(4<=n<=32766). Output Print the value of how many pairs are this even number can be divided into. Sample Input 1 1234 Sample Output 1 25
Take an hour from the user as input and tell it is time for which meal. • The user will input the number in a 24-hour format. So, 14 means 2 pm, 3 means 3 am, 18 means 6 pm, etc. • Valid inputs are 0 to 23. Inputs less than o or more than 23 are invalid in 24-hour clock. • Assume, Input will be whole numbers. For example, 3.5 will NOT be given as input. Inputs: Message to be printed 4 to 6: Breakfast 12 to 13: Lunch 16 to 17: Snacks 19 to 20: Dinner For all other valid inputs, say "Patience is a virtue" For all other invalid inputs, say "Wrong time" For example, If the user enters 4, your program should print the message "Breakfast". If the user enters 5, your program should print the message "Breakfast". If the user enters 6, your program should print the message "Breakfast". If the user enters 0, your program should print the message "Patience is a virtue". If the user enters 1, your program should print the message "Patience is a virtue". If the user enters 18, your program should…

Q2: A mercury thermometer having a time constant of 0.1 min is placed temperature bath at 100°F and allowed to come to equilibrium with the bath. At time t= 0, the temperature of the bath begins to vary sinusoidally about its average temperature of 100°F with an amplitude of 2°F If the frequency of oscillation is 10/π cycles/min, What is the phase lag?

Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. For example, it should output the individual digits of: •3456 as 3 4 5 6 sum = 18 •8030 as 8 0 3 0 sum = 11 •2345526 as 2 3 5 6 6 2 6 sum = 30 •-2345 as 2 3 4 5 sum = -14 To solve this problem consider the polynomial expansion of the integer, for example: 3456 = 3 * 10^3+ 4 * 10^2+ 5 * 10^1+ 6 * 10^0 To extract the digits from the right to left use: digit = number % 10 // update sum // output digit number = number / 10 // (use integer division) To extract the digits from left to right, use a similar strategy but you will need to know the highest power represented. This can be done by using two loops, the first loop extracts digits from right to left, keeping track of the number of times the loop executes and accumulating the sum. The second loop can use the value of the counter to extract digits from left to right for the final display. Make…
user_num1 and user_num2 are read from input. If user_num1 is less than 0, output 'user_num1 is negative'. If user_num2 is greater than 8, assign user_num2 with 5. Otherwise, output 'user_num2 is less than or equal to 8'. Click here for examples ● 1 user_num1 = int(input()) int(input()) 2 user_num2 = 3 | 4 user_num int (input) 5 user_num2 int (input 0) 6 if user_num1 8: 9 user_num2 = user_num2-5 10 else: 11 print (user_num2 is less than or equal to 8') 12 print('user_num2 is', user_num2)
Correct answer will be upvoted else downvoted. Computer science. You are given an integer n. Check if n has an odd divisor, more noteworthy than one (does there exist such a number x (x>1) that n is separable by x and x is odd). For instance, assuming n=6, there is x=3. Assuming n=4, such a number doesn't exist. Input The primary line contains one integer t (1≤t≤104) — the number of experiments. Then, at that point, t experiments follow. Each experiment contains one integer n (2≤n≤1014). If it's not too much trouble, note, that the input for some experiments will not squeeze into 32-cycle integer type, so you should use no less than 64-digit integer type in your programming language. Output For each experiment, output on a different line: "Indeed" if n has an odd divisor, more noteworthy than one; "NO" in any case. You can output "YES" and "NO" regardless (for instance, the strings yEs, indeed, Yes and YES will be perceived as certain).

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of fo* rn, where n is the distance (number of keys) from that key, and r is 2(1/12). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print (f'{your_value1:.2f} {your_value2:.2f} {your_value3:.2f} {your_value4:.2f} {your_value5:.2f}') Ex: If the input is: 440 (which is the A key near the middle of a piano keyboard), the output is: 440.00 466.16 493.88 523.25 554.37 Note: Use one statement to compute r = 2(1/12) using the pow function (remember to import the math module). Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4. 461710.3116374.qx3zqy7 LAB ACTIVITY 1 22 2 2.16.1: LAB: Musical note frequencies Type your code here. 111 main.py 0/10 Load default template...
Correct answer will be upvoted else downvoted. number is called 2050-number if it is 2050, 20500, ..., (2050⋅10k for integer k≥0). Given a number n, you are asked to represent n as the sum of some (not necessarily distinct) 2050-numbers. Compute the minimum number of 2050-numbers required for that. Input The first line contains a single integer T (1≤T≤1000) denoting the number of test cases. The only line of each test case contains a single integer n (1≤n≤1018) denoting the number to be represented. Output For each test case, output the minimum number of 2050-numbers in one line. If n cannot be represented as the sum of 2050-numbers, output −1 instead.
