Referring to Example 7.2.3, assume that records with the following ID numbers are to be placed in sequence into Table 7.2.1. Find the position into which each record is placed.

1. 417302072
2. 364981703
3. 283090787

(a)

To calculate:

The position into which below record is placed.

417−30−2072

Given information:

417−30−2072

Concept used:

Function: A function is a relation or expression involving one or more variables.

Since the hash function is defined as,

Hash(n)=nmod7

Calculation:

Consider 417−30−2072

As,

4173020727≃5.9614581

Evaluate,

Hash(417−30−2072)=417302072

(b)

To calculate:

The position into which below record is placed.

364−98−1703

(c)

To calculate:

The position into which below record is placed.

283−09−0787
