PHP SplHeap isCorrupted() Function
The SplHeap::isCorrupted() function is an inbuilt function in PHP which is used to tell if the heap is in a corrupted state.
Generally, the Heap Data Structure are of two types:
- Max-Heap: In a Max-Heap the key present at the root node must be greatest among the keys present at all of its children. The same property must be recursively true for all sub-trees in that Binary Tree.
- Min-Heap: In a Min-Heap the key present at the root node must be minimum among the keys present at all of its children. The same property must be recursively true for all sub-trees in that Binary Tree.
Syntax:
bool SplHeap::isCorrupted()
Parameters: This function does not accept any parameter.
Return Value: This function returns true if the heap is corrupted, false otherwise.
Below programs illustrate the SplHeap::isCorrupted() function in PHP:
Example 1:
PHP
<?php
$heap = new SplMinHeap();
$heap ->insert( 'System' );
$heap ->insert( 'GFG' );
$heap ->insert( 'ALGO' );
$heap ->insert( 'C' );
$heap ->insert( 'Geeks' );
$heap ->insert( 'GeeksforGeeks' );
var_dump( $heap ->isCorrupted());
?>
|
Output:
bool(false)
Example 2:
PHP
<?php
$heap = new SplMaxHeap();
$heap ->insert( 'System' );
$heap ->insert( 'GFG' );
$heap ->insert( 'ALGO' );
$heap ->insert( 'C' );
$heap ->insert( 'Geeks' );
$heap ->insert( 'GeeksforGeeks' );
var_dump( $heap ->isCorrupted());
?>
|
Output:
bool(false)
