**Merge Similar Items solution leetcode** – You are given two 2D integer arrays, `items1`

and `items2`

, representing two sets of items. Each array `items`

has the following properties:

`items[i] = [value`

where_{i}, weight_{i}]`value`

represents the_{i}**value**and`weight`

represents the_{i}**weight**of the`i`

item.^{th}- The value of each item in
`items`

is**unique**.

## [Solution] Merge Similar Items solution leetcode

Return *a 2D integer array* `ret`

*where* `ret[i] = [value`

_{i}, weight_{i}]*,* *with* `weight`

_{i}*being the sum of weights of all items with value*

`value`_{i}

.**Note:** `ret`

should be returned in **ascending** order by value.

**Example 1:**

Input:items1 = [[1,1],[4,5],[3,8]], items2 = [[3,1],[1,5]]Output:[[1,6],[3,9],[4,5]]Explanation:The item with value = 1 occurs in items1 with weight = 1 and in items2 with weight = 5, total weight = 1 + 5 = 6. The item with value = 3 occurs in items1 with weight = 8 and in items2 with weight = 1, total weight = 8 + 1 = 9. The item with value = 4 occurs in items1 with weight = 5, total weight = 5. Therefore, we return [[1,6],[3,9],[4,5]].

## [Solution] Merge Similar Items solution leetcode

Input:items1 = [[1,1],[3,2],[2,3]], items2 = [[2,1],[3,2],[1,3]]Output:[[1,4],[2,4],[3,4]]Explanation:The item with value = 1 occurs in items1 with weight = 1 and in items2 with weight = 3, total weight = 1 + 3 = 4. The item with value = 2 occurs in items1 with weight = 3 and in items2 with weight = 1, total weight = 3 + 1 = 4. The item with value = 3 occurs in items1 with weight = 2 and in items2 with weight = 2, total weight = 2 + 2 = 4. Therefore, we return [[1,4],[2,4],[3,4]].

**Example 3:**

Input:items1 = [[1,3],[2,2]], items2 = [[7,1],[2,2],[1,4]]Output:[[1,7],[2,4],[7,1]]Explanation:The item with value = 1 occurs in items1 with weight = 3 and in items2 with weight = 4, total weight = 3 + 4 = 7. The item with value = 2 occurs in items1 with weight = 2 and in items2 with weight = 2, total weight = 2 + 2 = 4. The item with value = 7 occurs in items2 with weight = 1, total weight = 1. Therefore, we return [[1,7],[2,4],[7,1]].

## [Solution] Merge Similar Items solution leetcode

`1 <= items1.length, items2.length <= 1000`

`items1[i].length == items2[i].length == 2`

`1 <= value`

_{i}, weight_{i}<= 1000- Each
`value`

in_{i}`items1`

is**unique**. - Each
`value`

in_{i}`items2`

is**unique**.
