A sentence is said to be balanced if there are equal numbers of vowels and consonants in it. The following pseudocode is executed using the "Words" dataset.

A sentence is said to be balanced if there are equal numbers of vowels and consonants in it. The following pseudocode is executed using the "Words" dataset. At the end of execution, Bcount counts the number of balanced sentences. But the pseudocode may have mistakes. Identify all such mistakes (if any). It is a Multiple Select Question (MSQ).
