Blind 75 - Reverse Bits

Get the last bit of value from the original. append to the reverse one. shift reverse one to the left. instead of adding, you can do `or` because after the shift last value will be 0. Imp - iterate 32 times only.

Nov 20, 2022

Blind 75 - Number of 1 Bits

Check if the last bit is 1 by (n&1). Do the right unsigned shift (logical shift >>>). Loop.

Nov 20, 2022

Blind 75 - Subtree of Another Tree

Check if root is same as subtree or root.left is same or root.right is same;

Nov 16, 2022

Blind 75 - Same Tree

Nov 16, 2022

Blind 75 - Reverse LinkedList

Similar to swapping two numbers. Start with prev as null and current and keep swapping next. Return prev because that's the last value.

Nov 16, 2022

Blind 75 - Merge Two-Sorted Lists

Iterate over both and store minimum one in current; Increment in the list from where minimum came. Once one of the lists is empty, empty the other one.

Nov 16, 2022

Blind 75 - Maximum Depth of Binary Tree

go to each depth, incrementing a depth counter by 1. return max of it.

Nov 16, 2022

Blind 75 - Linked List Cycle

Have a fast pointer and a slow pointer. fast increases by 2. slow increases by 1. if both become the same then the cycle exists. if fast one reaches end then no cycle exists.

Nov 16, 2022

Blind 75 - Invert Binary Tree

God-level solution - iterate.
If an opening bracket is found, put the closing bracket in a stack.
If the closing bracket is found, pop and check for equality.

Nov 6, 2022

Blind 75 - Valid Palindrome

Have 2 pointers. One at the start other at the end. Skip if `!Character.isLetterOrDigit` and compare with `Character.toLowerCase`

Nov 6, 2022

Blind 75 - Product of Array Except Self

Loop twice.
first right to left while multiplying.
Then second left to right while multiplying.
This can be done in a single array and one extra product variable

Nov 4, 2022

Blind 75 - Valid Anagrams

check if the length is the same.
find the difference in the count of letters in both numbers.
since there are only 26 letters, you can count in a single int array of 26.
index = char - 'a'

Oct 30, 2022

Blind 75 - Top K Frequent Elements - IMP

count all numbers. sort. and return top k. Use streams to make it cleaner. or use bucket sort.

Oct 30, 2022

Blind 75 - Group Anagram
