chain length of n , for example , a chain length of . your task is to write a program, for any pair of positive integers i and J, give the longest chain between I,J , of course, the longest chain length is by I, One of the positive integers between J is generated. Between IandJ here, I also include J.InputThe input file has only one row, that is, a positive integer i and J, separated by a space betweenI and J . 0 i ≤ J OutputThe file can have only one row, which is the longest chain length bet

the argument in the lastIndexOf () method is an empty string "", the result is the same as the return result of the length () method that called the string.③ truncate SUBSTRING SUBSTRING (start index) substring (start index, end index): The maximum value of the end index is the length of the string, and the substring length is the end index minus start index;Start index cannot be greater than end index④ remove before and after the space trim () format str2= "a ad fd a" System.out.println

values I selected a value of intwritable. The types of value values can also be set to nullwritable, but this makes the map task slow to execute, although the reduce task executes faster, but ultimately it is not worth the candle.There is no sort of action in our program, but the result of the output is orderly, because in the shuffle phase the sorting has been completed (one quick sort, one merge sort).Take a look at how Spark is done:object Numsortjob { = { = args (0) = args (

Easy Learning of JavaScript 12: JavaScript Object creation based on object-oriented (1)
This time, we will take a deeper look at the JavaScript object-oriented technology. Before learning, we need to explain some object-oriented terms.
This is what all faces object languages have in common. There are several object-oriented terms:
Object
The ECMA-262 defines an object as an unordered set of attributes, each
