Explain in detail about the Ruby arrays
Ruby arrays have many interesting and powerful methods. Besides indexing operations which go well beyond those discussed above, arrays have operations based on set operations (membership, union, intersection, and relative complement), string operations (searching, concatenation, and replacement), stack operations (pop and push), and queue operations (shift and append), as well as more traditional array-based operations (sorting, removing duplicates, reversing, and so forth). Arrays are also tightly bound up with Ruby's iteration mechanism.
The operations of the Symbol ADT The operations of the Symbol ADT are the following. a==b-returns true if and only if symbols a and bare identical. a symbol bin Unico
Program segment for deletion of any element from the queue delete() { int delvalue = 0; if (front == NULL) printf("Queue Empty"); { delvalue = front->value;
differentiate between indexing and hashing in file organization
Write an algorithm using pseudocode which takes temperatures input over a 100 day period (once per day) and output the number of days when the temperature was below 20C and the num
Q. Explain the term hashing? Explain any five well known hash functions. Ans: Hashing method provides us the direct access of record from the f
Midsquare Method :- this operates in 2 steps. In the first step the square of the key value K is taken. In the 2nd step, the hash value is obtained by deleting digits from ends of
Open addressing The easiest way to resolve a collision is to start with the hash address and do a sequential search by the table for an empty location.
Consider the file " search_2013 ". This is a text file containingsearch key values; each entry is a particular ID (in the schema given above). You are tosimulate searching over a h
Triangular Matrices Tiangular Matrices is of 2 types: a) Lower triangular b) Upper triangular
Indexed Sequential Files An index is inserted to the sequential file to provide random access. An overflow area required to be maintained to permit insertion in sequence. I
