Question

Which of the following are sorting functions for arrays in programming?

A) sort(), rsort(), arsort()
B) asort(), ksort(), krsort()
C) rsort(), ksort(), arsort()
D) sort(), asort(), krsort()

Answer 1

sort(), asort(), krsort() are three sorting functions used to sort arrays in programming.

Step-by-step explanation:

Three sorting functions for arrays in programming are:

1. sort(): This function sorts an array in ascending order.
2. asort(): This function sorts an array in ascending order while maintaining key-value associations.
3. krsort(): This function sorts an array in reverse order based on keys.

Using these functions, you can efficiently sort arrays in programming languages like PHP.

Answer 2

The correct sorting functions for arrays are in option B, which includes asort(), ksort(), and krsort().

Step-by-step explanation:

These functions, namely asort(), ksort(), and krsort(), are commonly used in programming, especially in languages like PHP. asort() sorts an array in ascending order while maintaining index association. ksort() sorts an array by key in ascending order, and krsort() sorts it by key in descending order.

These functions are essential for organizing array elements based on specific criteria. Option A lacks the complete set of correct sorting functions, and options C and D include incorrect combinations.

Therefore, option B is the accurate answer, encompassing the appropriate sorting functions for arrays.
