How do I change a character for multiple characters?

Question

Example : I have 3 coins = I have three coins.
Change the character '3' to the characters "three"

Answer 1

It is so simple just split the string just one char before the number and then join the number in string and then the remaining part.

Ex :

I have : 3 : conis
Convert 3-> three
Then join the 1st part, three and the 3rd part

=> I have three coins
