[LeetCode] Fraction to Recurring Decimal Given two integers representing the numerator and denominator of a fraction, return the fraction in string format. If the fractional part is 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 )".This problem is still difficult to implemen

1. Some data interaction elements such as button in order to avoid repeated submission of information, you can unbind after $.post or $.get, and then rebind after receiving the return, or set the button to Disabled2. In the Ajax may change some parameters, colleague parameters need to be assigned at bind time, after the parameter changes need unbind and then Re-bind3. The click behavior of an element is dynamically bound, there will be the possibility of duplicate binding, clicking on the elemen

Do a python program for regular server testing, Python to run its own detection time to execute? I thought about using a cron service.Encountered a problem python did not write the absolute path, did not execute, changed the absolute path is good. In fact, someone else's configuration file at the beginning of a path you put your path, such as:/usr/local/bin directory plus just fine.See how people realize the cron, other blog writing this flowchart for reference only, I feel this process is good.

we take to calculate division:(1) The first judgment sign (2) calculates the integer part, whether the surplus number, has, adds the decimal point '. ', continues to calculate; none, returns the result (3) the remainder of 0, and the denominator for division, counted in the results (R *=, ret + = to_string (r/d)) (4) If there are more, the remainder The calculated molecule (R%= D) ends the calculation until the loop is present or there is no remainder.5.
