• Repeat until all duplicates are removed

Printing all root to leaf paths in a binary search tree

• Traverse the tree recursively and keep track of the current path

• When a leaf node is reached, add the current path to the list of paths

• Print all the paths in the list

• Use an array of strings to store the paths

Find two integers in an array whose sum is closest to zero.

• Sort the array in ascending order.

• Initialize two pointers at the beginning and end of the array.

Count set bits in a 32-bit integer in linear time

• Use bit manipulation to count set bits

• Divide the integer into 16-bit chunks and count set bits in each chunk

• Use lookup tables to count set bits in each 8-bit chunk

• Use parallel processing to count set bits in multiple integers simultaneously

To determine the width of a binary tree using breadth-wise traversal, we need to count the number of nodes at each level.

• Perform a breadth-first traversal of the binary tree

• Count the number of nodes at each level

• Keep track of the maximum number of nodes seen at any level

• Return the maximum number of nodes seen

Files are preferred over databases for certain types of data and applications.
