*Steps of the Algorithm:*
1. **Prompt User for Principal, Rate, Time, and Number of Times Interest is Compounded**: Use the `input()` function to prompt the user to enter the principal amount, rate of interest, time period, and the number of times interest is compounded per year.
2. **Convert Inputs to Float**: Convert the input strings to floats using the `float()` function.
3. **Calculate Compound Interest**: Use the formula `A = P * (1 + r/n)^(n*t)` to calculate the compound interest, where `A` is the amount, `P` is the principal, `r` is the annual interest rate (decimal), `n` is the number of times interest is compounded per year, and `t` is the time in years.
4. **Calculate Total Interest**: Subtract the principal from the amount to get the compound interest.
5. **Print the Compound Interest**: Use the `print()` function to display the calculated compound interest.
*Detailed Steps:*
1. **Prompt User for Principal, Rate, Time, and Number of Times Interest is Compounded**:
Use the `input()` function to ask the user for the principal amount.
Use the `input()` function to ask the user for the annual interest rate.
Use the `input()` function to ask the user for the time period in years.
Use the `input()` function to ask the user for the number of times interest is compounded per year.
2. **Convert Inputs to Float**:
Use the `float()` function to convert the principal amount, annual interest rate, time period, and number of times interest is compounded from strings to floating-point numbers.
3. **Calculate Compound Interest**:
Use the formula `A = P * (1 + r/n)^(n*t)` to calculate the amount.
4. **Calculate Total Interest**:
Subtract the principal from the amount to get the compound interest.
5. **Print the Compound Interest**:
Use the `print()` function to display the compound interest.
