According to test instructions, this problem can be solved with a mob search, but the general search in this topic to each one with a cycle, the problem 2 number, each number 5 bits (million bits can be 0), supposedly 10 digits, 10 cycles, right? But here you just enumerate one number and the other number can be calculated. We certainly choose to enumerate the small number (in fact, which is the same), that is, the divisor, then
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

Recursion does not always mean inefficiency. In some scenarios, recursion is more efficient. For example, to calculate the m power of x, a conventional algorithm requires m multiplication. The following algorithm, however, the time complexity is reduced to O (logn)
