# Weighted Uniform Strings

A weighted string is a string of lowercase English letters where each letter has a *weight*. Character weights are to from to as shown below:

The

*weight of a string*is the sum of the weights of its characters. For example:- A
*uniform string*consists of a single character repeated zero or more times. For example,`ccc`

and`a`

are uniform strings, but`bcb`

and`cd`

are not.

Given a string, , let be the set of weights for all possible uniform contiguous substrings of string . There will be queries to answer where each query consists of a single integer. Create a return array where for each query, the value is `Yes`

if . Otherwise, append `No`

.

**Note:** The symbol denotes that is an element of set .

**Example**

.

Working from left to right, weights that exist are:

```
string weight
a 1
b 2
bb 4
c 3
cc 6
ccc 9
d 4
dd 8
ddd 12
dddd 16
```

Now for each value in , see if it exists in the possible string weights. The return array is `['Yes', 'No', 'No', 'Yes', 'No']`

.

**Function Description**

Complete the *weightedUniformStrings* function in the editor below.

weightedUniformStrings has the following parameter(s):

- *string s:* a string

- *int queries[n]:* an array of integers

**Returns**

- *string[n]:* an array of strings that answer the queries

**Input Format**

The first line contains a string , the original string.

The second line contains an integer , the number of queries.

Each of the next lines contains an integer , the weight of a uniform subtring of that may or may not exist.

**Constraints**

- will only contain lowercase English letters, ascii[a-z].

**Sample Input 0**

```
abccddde
6
1
3
12
5
9
10
```

**Sample Output 0**

```
Yes
Yes
Yes
Yes
No
No
```

**Explanation 0**

The weights of every possible *uniform substring* in the string `abccddde`

are shown below:

We print `Yes`

on the first four lines because the first four queries match weights of uniform substrings of . We print `No`

for the last two queries because there are no uniform substrings in that have those weights.

Note that while `de`

is a substring of that would have a weight of , it is *not a uniform substring*.

Note that we are only dealing with contiguous substrings. So `ccc`

is not a substring of the string `ccxxc`

.
