Answer:
Answer explained below
Explanation:
This problem can be represented on a graph by considering each state (or configuration) of the pair of containers as a vertex of the graph. We will be having 24 vertices, since the first container can have 0, 1, 2 or 3 gallons and the second can have 0, 1, 2, 3, 4 or 5 gallons of water. So, we will be having vertices like (0, 0), (0, 1), (0,5), (1, 0), (2, 3), (5, 5) etc.
The edges will be directed, and a vertex will be having an edge to it from another vertex if the configuration of the later vertex can be reached from the former vertex by any one of the legal moves. For example, from (2, 3) we can get (0, 5) by transferring the contents of the first container to the second. So there will be an edge from (2, 3) to (0, 5).

The function <u>strpos()</u> is a function in php that returns the position of the first occurrence of a particular substring in a string. Positions are counted from 0. The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.
In this case, the string is "Get Well Soon!" while the substring is "Well"
Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".
Therefore, the function strpos("Get Well Soon!", "Well") will return 4.
Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.
Answer:
public static String onlyDigits(String in){
String digitsOnly = in.replaceAll("[^0-9]", "");
return digitsOnly;
}
A Complete program is wrtten in the explanation section
Explanation:
public class TestClass {
public static void main(String[] args) {
String a = "-jaskdh2367sd.27askjdfh23";
System.out.println(onlyDigits(a));
}
public static String onlyDigits(String in){
String digitsOnly = in.replaceAll("[^0-9]", "");
return digitsOnly;
}
}
The output: 23672723
The main logic here is using the Java replaceAll method which returns a string after replacing all the sequence of characters that match its argument, regex with an empty string
