The string you'll received as a parameter has too many characters. Your job is toRemove characters from the string in the following order:1. Find the smallest i such that the i-th character and the (i+1)-th character of the string is same.2. If There is no such I, end the process.3. Remove the i-th and the (i+1)-th character of the string, and repeat from 1.For example, if the parameter is "AYQQYJJJ", she'll change the string as follows: "AYQQYJJJ", "AYYJJJ", AJ JJ "," AJ ".Return the resulting

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) ".

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 ".

All types of Java applications typically need to plan for recurring tasks. Enterprise applications need to schedule daily logs or nightly batch processes. A J2SE or J2ME calendar application needs to schedule the alarm time according to the user's agreement. However, the standard scheduling class Timer and timertask do not have enough flexibility to support the type of scheduled tasks that are typically required. In this article, Java developer Tom Wh
