Consider the Binary Tree: Pre-order traversal(root) is traversing the node then left sub-tree of the node and then the right sub-tree of the node. So the pre-order traversal of above tree will be: 1 2 4 5 3 6 7 In-order traversal(root) is traversing the left sub-tree of the node then the node ...

For example if the inputs are: Example:1 a) b) Output should be true. Example:2 If the inputs are: a) b) Output should be false. Pseudo code for the same: boolean sameTree(node root1, node root2){ if(root1 == NULL && root2 == NULL) return true; if(root1 == NULL ...

P( glasses | reading ) = Count( reading glasses ) / Count( reading ) We count the sequences reading glasses and glasses from corpus and compute the probability.

function getCombinations(params, combinationsResults){ if(params.length == 0) return combinationsResults; var head = params[0]; var tail = params.slice(1); var combinationsResultsCurrent = []; if(Array.isArray(head)){ _.uniq(head).forEach(function(item){ ...

The latest find is always the one the availability check will work against - a unsuccesful find will make AVAILABLE return false: DEFINE TEMP-TABLE tt NO-UNDO FIELD nr AS INTEGER. CREATE tt. tt.nr = 1. CREATE tt. tt.nr = 2. CREATE tt. tt.nr = 3. DISPLAY AVAILABL tt. // yes (tt w...

The BigDecimal class contains an internal cache of frequently used numbers e.g. 0 to 10. The BigDecimal.valueOf() methods are provided in preference to constructors with similar type parameters i.e. in the below example a is preferred to b. BigDecimal a = BigDecimal.valueOf(10L); //Returns cached O...

BigDecimal provides static properties for the numbers zero, one and ten. It's good practise to use these instead of using the actual numbers: BigDecimal.ZERO BigDecimal.ONE BigDecimal.TEN By using the static properties, you avoid an unnecessary instantiation, also you've got a literal in you...

Since 1.7 there's a java.util.BitSet class that provides simple and user-friendly bit storage and manipulation interface: final BitSet bitSet = new BitSet(8); // by default all bits are unset IntStream.range(0, 8).filter(i -> i % 2 == 0).forEach(bitSet::set); // {0, 2, 4, 6} bitSet.set(3);...
