I have an array of strings
I would like to print all characters that occur equal times in each index so in above case I would print
bb because they occur twice in both indexes and a occurs once and twice in first and second index respectively.
Keep track of only the characters in the first index and
because we would not need to worry about other letters anyway.
So in above case I would keep track of letter
b and check if
they occur same time in the next indexes.
Can someone suggest a better way if possible or am I on right track?
