The coding test consists of multiple-choice questions and one medium-hard level coding question.
The angle between the minute and hour hand of a clock at 3:45 is 157.5 degrees.
Calculate the angle formed by the hour hand from 12 o'clock position to 3:45 position (135 degrees)
Calculate the angle formed by the minute hand from 12 o'clock position to 3:45 position (22.5 degrees)
Subtract the smaller angle from the larger angle to get the angle between the two hands (157.5 degrees)
Indexing in DBMS is a technique used to improve the performance of queries by allowing faster retrieval of data.
Indexes are data structures that store a small portion of the data set in an easily searchable format.
They help in speeding up the data retrieval process by reducing the number of disk accesses needed.
Indexes can be created on one or more columns of a table to improve the performance of SELECT queries.
