Find if one string is "oneEditAway" from another string
Implement method oneEditApart that return boolean: true, if using one operations (insert or remove or replace) we can modify one string to get another. False otherwise. // Signature: boolean oneEditApart(String s1, String s2) // Allowing operations insert remove replace Example: oea("cat", "cut") => true // replace "u" -> "a" oea("cat", "cuts") => false // no operations oea("ca", "ca") => false // no operations oea("cats", "cat") => true // remove "s" oea("cat", "at") => true // insert "c" oea("cat", "cbat") => true // remove "b"
There was a tree and I was supposed to make a double linked list from the tree using a pre order traversal.
A and B are 32 bit numbers with first 16 bits valid in A and next 16 bits valid in B. (The non-valid bits aren't necessarily 0). WAP that adds A and B without using arithmetic operator.
Is having more cores in processor always solve the problem of throughput
Multiply two big ints.
Write a function to find how many valid letters are in a string of digits give the mapping: a -> 1 b -> 2 ... z - > 26 ex) '123' =>1, 12, 23 => 'a', 'l', 'w'
you have a list of people, and a function that return true/false if one person knows the second person. write a function that finds a VIP, which everybody knows and he doesn't know anybody else.
You have a 4 x 4 board with words. For example: A B G H O L L E E R T Y G E F Y You need to write a function that finds if a certain word exists in the board. The rules are as followed: 1. Each character needs to be close to one another (neighbor cell). For example: The function will return false for the word HERE but true for the word HEY.
