Vector : The Standard Template Library (STL) includes the collection of data types and algorithms which can be used by the programmer in their programs. A special data type called vector is offered by STL which is useful for standard arrays. A vector stores the elements or values in sequence order and the values are stored in continuous memory locations. The subscript operator “[]” in the vector helps to read the content of each element. Initialization of vector: In C++, the vector is initialized with the respective value as like the array but it does not use the “=” operator before the list and uses the keyword “vector”. The initialization list values are enclosed with the braces. Consider the following statement: //Declaring a vector with four values vector <int> values {40, 32, 15, 17}; In the above line, the keyword “vector” represents the vector declaration, “<int>” represents that the vector holds integer type values, “values” represents the name of the vector, and the values inside the braces refers the values of the vector “values”.

Program Plan Intro

Vector:

The Standard Template Library (STL) includes the collection of data types and algorithms which can be used by the programmer in their programs.

A special data type called vector is offered by STL which is useful for standard arrays.

A vector stores the elements or values in sequence order and the values are stored in continuous memory locations.

The subscript operator “[]” in the vector helps to read the content of each element.

Initialization of vector:

In C++, the vector is initialized with the respective value as like the array but it does not use the “=” operator before the list and uses the keyword “vector”.

The initialization list values are enclosed with the braces.

Consider the following statement:

//Declaring a vector with four values

vector <int> values {40, 32, 15, 17};

In the above line, the keyword “vector” represents the vector declaration, “<int>” represents that the vector holds integer type values, “values” represents the name of the vector, and the values inside the braces refers the values of the vector “values”.

We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.
