you can use strstr()
there is no such method using string copy
a write the algorithm to concatenate two given string
One way to do this is to convert the number to a String, then use the corresponding String method to find out the length of the String.
You usually do not need to delete a String, since when the program no longer refers to it, the garbage collector will clean it up.
.... String line = "This is example program with spaces"; String[] tokens = line.split(" "); System.out.println(tokens.length-1); .......
I believe the term "proper set" is not use in math. A "proper subset" is a subset of a given set, that is not equal to the set itself.
Given a set S, T is a proper subset of Sifany element of T is an element of S and there is at least one element of S that is not in T.The first condition ensures that T is a subset. The second ensures that it is a proper subset.
The only proper subset of a set comprising one element, is the null set.
The set {1, 3} is a proper subset of {1, 2, 3}.The set {a, b, c, d, e} is a proper subset of the set that contains all the letters in the alphabet.All subsets of a given set are proper subsets, except for the set itself. (Every set is a subset of itself, but not a proper subset.) The empty set is a proper subset of any non-empty set.This sounds like a school question. To answer it, first make up any set you like. Then, as examples of proper subsets, make sets that contain some, but not all, of the members of your original set.
A set "A" is said to be a subset of "B" if all elements of set "A" are also elements of set "B".Set "A" is said to be a proper subset of set "B" if: * A is a subset of B, and * A is not identical to B In other words, set "B" would have at least one element that is not an element of set "A". Examples: {1, 2} is a subset of {1, 2}. It is not a proper subset. {1, 3} is a subset of {1, 2, 3}. It is also a proper subset.
A subset, A, of a given a set S, consists of none or more elements that belong to S.
Given a set, S, a subset A of S is set containing none or more elements of S. So by definition, the subset A is a set.If there exists some element that is in S but not in A then A is a pro[er subset of S.
Given a set, S, a subset A of S is set containing none or more elements of S. So by definition, the subset A is a set.If there exists some element that is in S but not in A then A is a pro[er subset of S.
If the set has n elements then it has 2n subsets.
there is no such method using string copy
given any set of n objects, there are 2^n subsets. This comes from the fact that each item is either in or not in any given subset. So for all n objects, each one has two possibilities, either it is or is not in a subset. Then 2^n come from the multiplication principle.
Reverse the string and compare it to the original. If they match, then it is a palindrome.
