Bessie the cow has arranged a string of N rocks, each containing a single letter of the alphabet, that she wants to build into a fashionable necklace.
Being protective of her belongings, Bessie does not want to share her necklace with the other cow currently living on her side of the barn. The other cow has a name that is a string of M characters, and Bessie wants to be sure that this length-M string does not occur as a contiguous substring anywhere within the string representing her necklace (otherwise, the other cow might mistakenly think the necklace is for her). Bessie decides to remove some of the rocks in her necklace so that the other cow's name does not appear as a substring. Please help Bessie determine the minimum number of rocks she must remove.
The modified necklace should be "abbaa".
