- Please do this in JAVA PROGRAMMING. Given: List L of pairs of charactersString SOutput: TRUE if S is a valid string, FALSE otherwise. A string is considered valid if each character in the string can be paired with another character in the string, where the pair belongs to the input list L. Furthermore, two pairs cannot cross each other. In other words, a pair most completely enclose another, or be completely separate. Design and implement an efficient dynamic programming solution to this problem. Examples: Input L: (a b) (b c) (c d) (a a) Input S: aaba Output: True (pairs shown color-coded: aaba, "aa" fully encloses "ab") Input L: (a b) (b c) (c d) (a a) Input S: abcaad Output: True (pairs shown color-coded: abcaad, "ab" is separate from the other pairs) Input L: (a b) (b c) (c d) (a a) Input S: acbd Output: False (acbd is not valid because the pairs cross each other.) Input L: (a b) (b c) (c d) (a a) Input S: aaac Output: FalsePlease implement in Java implement a keyed bag in which the items to be stored are strings (perhaps people’s names) and the keys are numbers (perhaps Social Security or other identification numbers). So, the in- sertion method has this specification: public void insert(String entry, int key);// Precondition: size( ) < CAPACITY, and the // bag does not yet contain any item// with the given key.// Postcondition: A new copy of entry has// been added to the bag, with the given key. When the programmer wants to remove or retrieve an item from a keyed bag, the key of the item must be specified rather than the item itself. The keyed bag should also have a boolean method that can be used to determine whether the bag has an item with a specified key. In a keyed bag, the pro- grammer using the class specifies a particular key when an item is inserted. Here’s an implementation idea: A keyed bag can have two private arrays, one that holds the string data and one that holds the corresponding…Design a Java class named LinearEquation for a 2-by-2 system of linear equations:ax + by = e x=(ed-bf)/(ad-bc)cx + dy = f y=(af-ec)/(ad-bc) The class contains:• Private double data fields a, b, c, d, e, and f.• A constructor with the arguments for a, b, c, d, e, and f.• Six getter methods for a, b, c, d, e, and f.• Methods getX() and getY() that return the solution for the equation.• A method named isSolvable() that returns true if ad - bc is not 0. The method isSolvable() willbe called in the main, if it returns true display the calculated values for x and y by calling getX()and getY(). If the call to isSolvable() returns false, display a message that “the equation has nosolution”. Write a Java program that prompts the user to enter a, b, c, d, e, and f and displays the result. After the valuesfor a through f are entered, create a LinearEquation object. Check to seeIf ad - bc is 0, report that “The equation has no solution”, otherwise print out the values for x and y.
