Largest Combination With Bitwise AND Greater Than Zero - Count Individual Bits [JS]

By on

Description 

Solution: Count Individual Bits

To have a bitwise AND sum larger than 0, we only need one bit that hasn't been cancelled out.
Populate an array count, where count[i]indicates the number of candidates where the ith bit is 1.
Get the maximum count.

Time Complexity: O(n)
Space Complexity: O(1)

var largestCombination = function(candidates) {
  let count = Array(32).fill(0);
  for (let num of candidates) {
    let number = num, pos = 0;
    while (number > 0) {
      let bit = number & 1;
      if (bit) count[pos]++;
      number = number >> 1;
      pos++;
    }
  }
  return Math.max(...count);
};

Maximum Value of an Ordered Triplet II - Two Solutions [JS]

By on
Description   Solution 1: Prefix Max Summary: Anchor at  nums[j] . We want  nums[i]  and  nums[k]  to be as larger as possible, and  nums[j]  to be as small as possible to ensure the maximum value. Calculate the maximum value on the right of each index  i :  maxRight[i]  = maximum value from index  i  to  n - 1 Go through  nums  from left to right and take each element as  nums[j] . Keep track of the maximum value on the left. Get the maximum value on the left and right of  nums[j] . Record the maximum value. Time Complexity:  O(n) Space Complexity:  O(n) var maximumTripletValue = function ( nums ) { let n = nums.length, maxRight = [...nums]; for ( let i = n - 2 ; i >= 0 ; i--) { maxRight[i] = Math .max(nums[i], maxRight[i + 1 ]); } let maxLeft = 0 , ans = 0 ; for ( let j = 0 ; j < n; j++) { if (j > 0 && j < n - 1 ) { ans = Math .max(an...

Maximum Sum of Distinct Subarrays With Length K - Sliding Window w/ Two Pointers & Set [JS]

By on
Description  Solution: Sliding Window w/ Two Pointers & Set Maintain a sliding window of unique numbers with maximum size of  k . We can store the numbers in the window in a hashset. When we move the right pointer up, move the left pointer up until: all numbers in the window are unique the window size  <= k Time Complexity:  O(n)  246ms Space Complexity:  O(k)  71.5MB var maximumSubarraySum = function ( nums, k ) { let set = new Set (), sum = 0 ; let ans = 0 , n = nums.length; for ( let j = 0 , i = 0 ; j < n; j++) { sum += nums[j]; while (set.has(nums[j]) || j - i >= k) { sum -= nums[i]; set.delete(nums[i]); i++; } set.add(nums[j]); if (j - i + 1 === k) ans = Math .max(ans, sum); } return ans; };

Sum of Prefix Scores of Strings - Trie [JS]

By on
Description   Solution: Trie Store each word in a trie. For every node in the trie, keep track of the number of words it is part of. Since we stored the count of words on every node, we can calculate the count of every prefix for every word on the fly. n = number of words ,  m = max(words[i].length) Time Complexity:  O(nm) Space Complexity:  O(26^m)  at worst var sumPrefixScores = function ( words ) { let trie = new Trie(); for ( let word of words) { trie.add(word); } let n = words.length, res = Array (n); for ( let i = 0 ; i < words.length; i++) { res[i] = trie.getScore(words[i]); } return res; }; class TrieNode { constructor ( ) { this .children = {}; this .count = 0 ; } } class Trie { constructor ( ) { this .root = new TrieNode(); } add ( word ) { let node = this .root; for ( let i = 0 ; i < word.length; i++) { node = node.children; let char = word[i]; if (...

Maximum Count of Positive Integer and Negative Integer - Binary Search [JS]

By on
Description  Solution: Binary Search Since  nums  is sorted, we can use binary search: Binary search for the index of the rightmost negative number. Binary search for the index of the leftmost positive number. Based on the indexes we can find the amount of negative and positive numbers. Time Complexity:  O(log(n))  64ms Space Complexity:  O(1)  43.7MB var maximumCount = function ( nums ) { return Math .max(upper_bound(nums), lower_bound(nums)); }; // binary search for the rightmost negative number function upper_bound ( nums ) { let low = 0 , high = nums.length - 1 ; while (low < high) { let mid = Math .ceil((low + high) / 2 ); if (nums[mid] < 0 ) low = mid; else high = mid - 1 ; } return nums[ 0 ] >= 0 ? 0 : low + 1 ; } // binary search for the leftmost positive number function lower_bound ( nums ) { let low = 0 , high = nums.length - 1 ; while (low < high) { let mid = Math .floor((low + hi...

Count Subarrays With Median K - Count Left & Right Balance [JS]

By on
Description   Solution: Count Left & Right Balance For a subarray to have median of  k : The subarray must contain  k . k  must be the middle element (if odd) or lower mid element (if even). Create subarrays revolving around  nums[i] = k . How do we find whether  k  is the mid/lower mid element? Starting from  k , count the "balance" on the left and right of  k . If  nums[i] < k , add  -1  to the balance. If  nums[i] > k , add  1  to the balance. If  k  is the mid element, the left balance + right balance =  0 . If  k  is the lower mid element, left balance + right balance =  1 . Store the count of left balances in a hashmap. Go through each right balance, Balance = 0 : Count the number of left balances that are equal to ( -right balance ) Balance = 1 : Count the number of left balances that are equal to ( -right balance + 1 ) Time Complexity:  O(n) Space Complexity:...
