Given a string s, return the string after replacing every uppercase letter with the same lowercase letter.
Example 1:
Input: s = "Hello " Output: "hello "
Example 2:
Input: s = "here " Output: "here "
Example 3:
Input: s = "LOVELY " Output: "lovely "
Constraints:
1 <= s.length <= 100s consists of printable ASCII characters.program main
implicit none
character(len=100) :: s
s = "Hello "
call solve(s)
write (*,*) s
s = "here "
call solve(s)
write (*,*) s
s = "LOVELY "
call solve(s)
write (*,*) s

def toLowerCase(s: str) -> str:
return s.lower()
The algorithm goes through each character in the input string and checks if the character is an uppercase letter. If it is, it converts the letter to lowercase, otherwise it keeps the character unchanged. In C++ and Java, we use a loop to go through each character and update it in-place. In Python, the built-in str.lower() function is used. In JavaScript, we need to create a new string by concatenating the resulting characters. For each language, the modified string is returned.
