This topic has not been done since there are too many corner case to consider.1. Divisor equals 0.2. Dividend equals 0.3. Is the result negative?4. When dividend equals Integer.min_value and divisor equals-1, the result would overflow. Convert result to long and then to Integer.5. Divided by divisor * 2 ^ n to avoid exceeding time limit6. There is a to convert divisor and

1. Question
2. Answer 2.1. method 1
The question requires that multiplication, division, and Division operations cannot be used, but we canDivision is transferred to the logarithm Field.
$ \ Frac {A} {B} = e ^ {\ frac {LNA} {LNB} = e ^ {LNA-LNB} $
In this way, it is converted to exponential, logarithm, and subtraction operations. Because we can only take the logarithm of a positive integer, we must first take the absolute values of both numbers, and then add the symbol.
At the same time, the que

If you do not have a ten-year reserve for a stock, do not hold it for ten minutes.-- Investment master Warren Buffett
We often say that stocks are high-risk, high-reward investment tools. Likewise, it can be proved that stock funds also have high-risk and high-reward features and are suitable for long-term investment. In stock fund, it can be further subdivided into small categories such as positive growth, growth, growth income, and stock income fund. In the Fund terminology, "Growth" refers t

problem:Given integers representing the numerator and denominator of a fraction, return the fraction in string format.If the fractional part was repeating, enclose the repeating part in parentheses.For example,
Given numerator = 1, denominator = 2, return "0.5".
Given numerator = 2, denominator = 1, return "2".
Given numerator = 2, denominator = 3, return "0. (6) ".
