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
anda
are uniform strings, butbcb
andcd
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].

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
.
