Introduction To Algorithm
The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results.
Advantages of Algorithms:
- It is easy to understand.
- Algorithm is a step-wise representation of a solution to a given problem.
- In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program.

Problem:
The diagram below depicts some beautiful strings:
Perform queries where each query consists of some integer string . For each query, print whether or not the string is beautiful on a new line. If it is beautiful, print YES x, where is the first number of the increasing sequence. If there are multiple such values of , choose the smallest. Otherwise, print NO.
Function Description
Complete the separateNumbers function in the editor below.
separateNumbers has the following parameter:
- s: an integer value represented as a string
Prints
– string: Print a string as described above. Return nothing.
Input Format
The first line contains an integer , the number of strings to evaluate.
Each of the next lines contains an integer string to query.
Constraints
Sample Input 0
7 1234 91011 99100 101103 010203 13 1
Sample Output 0
YES 1 YES 9 YES 99 NO NO NO NO
Explanation 0
The first three numbers are beautiful (see the diagram above). The remaining numbers are not beautiful:
- For , all possible splits violate the first and/or second conditions.
- For , it starts with a zero so all possible splits violate the second condition.
- For , the only possible split is , which violates the first condition.
- For , there are no possible splits because only has one digit.
Sample Input 1
4 99910001001 7891011 9899100 999100010001
Sample Output 1
YES 999 YES 7 YES 98 NO
