# Number of Non-Overlapping Sublists With Sum of Target - Google Top Interview Questions

### Problem Statement :

```You are given a list of integers nums and an integer target.

Return the maximum number of non-overlapping, non-empty sublists that exist such that each sublist's sum is target.

Constraints

0 ≤ n ≤ 100,000 where n is the length of nums

Example 1

Input

nums = [4, 3, 7, 5, -3, 10]

target = 7

Output

3

Explanation

We can have [4, 3], [7] and [-3, 10]```

### Solution :

```                        ```Solution in C++ :

int solve(vector<int>& nums, int target) {
unordered_set<int> m{0};
int ans = 0;
for (int i = 0, s = 0; i < nums.size(); i++) {
s += nums[i];
if (m.find(s - target) != m.end()) {
ans++;
m.clear();
}
m.insert(s);
}
return ans;
}```
```

```                        ```Solution in Python :

class Solution:
def solve(self, nums, target):
s = 0
a = {0: 0}
n = len(nums)
b = [0] * (n + 1)
for i, x in enumerate(nums):
s += x
b[i + 1] = b[i]
if s - target in a:
b[i + 1] = max(b[i + 1], b[a[s - target]] + 1)
a[s] = i + 1
return b[n]```

## Super Maximum Cost Queries

Victoria has a tree, T , consisting of N nodes numbered from 1 to N. Each edge from node Ui to Vi in tree T has an integer weight, Wi. Let's define the cost, C, of a path from some node X to some other node Y as the maximum weight ( W ) for any edge in the unique path from node X to Y node . Victoria wants your help processing Q queries on tree T, where each query contains 2 integers, L and

## Contacts

We're going to make our own Contacts application! The application must perform two types of operations: 1 . add name, where name is a string denoting a contact name. This must store name as a new contact in the application. find partial, where partial is a string denoting a partial name to search the application for. It must count the number of contacts starting partial with and print the co

## No Prefix Set

There is a given list of strings where each string contains only lowercase letters from a - j, inclusive. The set of strings is said to be a GOOD SET if no string is a prefix of another string. In this case, print GOOD SET. Otherwise, print BAD SET on the first line followed by the string being checked. Note If two strings are identical, they are prefixes of each other. Function Descriptio

## Cube Summation

You are given a 3-D Matrix in which each block contains 0 initially. The first block is defined by the coordinate (1,1,1) and the last block is defined by the coordinate (N,N,N). There are two types of queries. UPDATE x y z W updates the value of block (x,y,z) to W. QUERY x1 y1 z1 x2 y2 z2 calculates the sum of the value of blocks whose x coordinate is between x1 and x2 (inclusive), y coor

## Direct Connections

Enter-View ( EV ) is a linear, street-like country. By linear, we mean all the cities of the country are placed on a single straight line - the x -axis. Thus every city's position can be defined by a single coordinate, xi, the distance from the left borderline of the country. You can treat all cities as single points. Unfortunately, the dictator of telecommunication of EV (Mr. S. Treat Jr.) do

## Subsequence Weighting

A subsequence of a sequence is a sequence which is obtained by deleting zero or more elements from the sequence. You are given a sequence A in which every element is a pair of integers i.e A = [(a1, w1), (a2, w2),..., (aN, wN)]. For a subseqence B = [(b1, v1), (b2, v2), ...., (bM, vM)] of the given sequence : We call it increasing if for every i (1 <= i < M ) , bi < bi+1. Weight(B) =
