In 31—39, write a regular expression to define the given set of strings. Use the shorthand notations given in the section whenever convenient. In most cases, your expression will describe other strings in addition to the given ones, but try to make your answer fit the given strings as closely as possible within reasonable space limitations.

37. All United States social security numbers (which consist of three digits, a hyphen, two digits, another hyphen, and finally four more digits), where the final four digits start with a 3 and end with a 6.

Write a regular expression to define the given set of strings. Use the shorthand notations given in the section when ever convenient. In most cases, your expression will describe other strings in addition to the given ones. but try to make your answer fit the given strings as closely as possible wïthin reasonable space limitations.

All United States social security numbers (which consist of three digits. a hyphen, two digits, another hyphen, and finally four more digits), wtiere the final four digits start with a 3 and end with a 6.

Given information:

All United States social security numbers (which consist of three digits. a hyphen, two digits, another hyphen, and finally four more digits), wtiere the final four digits start with a 3 and end with a 6.

Concept used:

Every string contains exactly one of the vowels a,e,i,o,u

Calculation:

The set of strings has 3 digits, a hyphen, 2 digits. another hyphen, and 4 more digits.

The final four digits start with a 3 and end with a 6.

The objective is to write corresponding regular expression using shorthand notation.

The number digits can be denoted with the character class [0−9]=[0|1|
