Common Mistakes

Using Replace instead of Split will change text but not split it.

Trim removes spaces only at the start or end, not between words.

The Split method breaks a string into parts based on the separator. Here, space (' ') splits the text into words.

Common Mistakes

Using TrimStart instead of Trim leaves spaces at the end.

Splitting before replacing spaces causes wrong results.

Replace changes spaces to dashes, Trim removes dashes at ends, Split breaks string by dashes.
