This advanced-level assessment simulates real-world coding challenges, testing your ability to analyze problems, implement optimal solutions, and leverage C++?s full capabilities in performance-critical applications.

Example Question:

Coding

Bobby is inventing a new language in which there are only four words: A, B, AB, and BA. He asks his friend to write a sentence s in this language. He also asks his friend to give the count of each word in the sentence. His friend gives Bobby an array counts of size 4, denoting the number of words A, B, AB, and BA, respectively. Given s and counts, help Bobby find whether these form a valid string or not. Return 1 if s is a valid string with a word count equal to counts and return 0 otherwise. Note that there could be multiple interpretations of s given counts.

Example:

s = "B"
counts = 1,0,0,0
Clearly, "B" can't consist of a single word A
So the answer is 0.

s = "ABAB"
counts = 1,1,0,1
it's possible that s consists of one word A, one word B, and one word BA
A+BA+B=ABAB.
Therefore, the answer is 1.
