• Last Updated : 24 Jun, 2021

Given an array of integers, find the maximum and minimum in it.
Examples:

```Input : arr[] = {2, 3, 1, 6, 7}
Output : Maximum integer of the given array:7
Minimum integer of the given array:1

Input  : arr[] = {1, 2, 3, 4, 5}
Output : Maximum integer of the given array : 5
Minimum integer of the given array : 1```

Approach 1 (Simple) : We simply traverse through the array, find its maximum and minimum.

PHP

 ` ``\$array``[``\$i``])``           ``\$min` `= ``\$array``[``\$i``];``    ``return` `\$min``;      ``}` `// Driver code``\$array` `= ``array``(1, 2, 3, 4, 5);``echo``(getMax(``\$array``));``echo``(``"\n"``);``echo``(getMin(``\$array``));``?>`

Output:

```5
1```

Approach 2 (Using Library Functions) : We use library functions to find minimum and maximum.

1. Max():max() returns the parameter value considered “highest” according to standard comparisons. If multiple values of different types evaluate as equal (e.g. 0 and ‘abc’) the first provided to the function will be returned.

2. Min():min() returns the parameter value considered “lowest” according to standard comparisons. If multiple values of different types evaluate as equal (e.g. 0 and ‘abc’) the first provided to the function will be returned.

Output:

```5
1```
