java - Checking if two strings are permutations of each other -

-

To determine whether two strings are permutations of each other

< Div class =

  • Compare the results to see if they are the same.

    • Edit:

    The above method is quite efficient - O (n * log (n)) and, as shown by others Is the standard java API Even more efficient (but more than that) the calculation and comparison of the occurrence of each character, will be used as an index of values ​​in the form of an index.

    I do not think this is an effective way of doing this recursively

    • If both strings meet the same character, then the correct return
      • Otherwise: <
    • Remove a letter from the first letter
    • View the second string for the occurrence of this character
    • If it does not exist then False return
    • Otherwise, delete the deleted character and apply the rearranged algorithm to those who have two strings Please.

    c# - TypeConverter in propertygrid only converts from string, not to -

    -
    When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends.
