### String Operations and Methods

This table pairs string operations with their corresponding string methods. Each operation's description is listed alongside its matching letter and method.

| #  | String Operation                                                                                                   | Matching Letter | String Methods                                         |

| 5  | Checks for the occurrence of the substring and returns True if found and False if not found - case sensitive       | B               | String.Contains(substring)                             |
| 6  | Checks for the occurrence of the substring and if found, returns the start index; if not, returns -1; search begins at first location | C               | String.IndexOf(substring)                               |

| 8  | Extracts from a string the specified number of characters starting at start index location and returns the extracted characters | K               | String.Substring(start index, # of characters to extract) |
| 9  | Removes from a string the specified number of characters to remove starting at start index and returns a string with the characters removed | D               | String.Remove(start index, # of characters to remove)  |
| 10 | Removes specified characters from anywhere in a string and returns a string with the characters removed             | N               | String.Trim("character 1", "character 2", ..., "character n") |
