Removal of words on the list

[authera]

Good afternoon! There is a list of different symbols:

• 84 000888sWord545
• 324 tipsWordAoshua
• LostWordFovish

Should be cut Word and everything after him. The number of symbols before and after a specific word may vary.

I've read various resources, but only editing has a certain symbol, I'll be very good!

Let's set up a method. RemoveWords(str, word)♪

In the body of the method, the index is obtained by the method IndexOf(str, word) and Remove(startIndex, length) remove all the symbols.
