String s = "thisIsAVariable"; //INPUT

char ch[] = s.toCharArray();

// 1st approach
		String str = "";
		for (int i = 0; i < ch.length; i++) {
			if (Character.isUpperCase(ch[i])) {
				str += "_";
				str += ch[i];
			} else
				str += ch[i];
		}
		System.out.println(str.toLowerCase()); //O/P: this_is_a_variable

new_s = ""
i = 0
while i < len(s):
    if s[i] == "_":
        new_s = new_s + (s[i] + s[i + 1]).replace(s[i] + s[i + 1], s[i + 1].upper())
        i = i + 2
    else:
        new_s = new_s + s[i]
        i = i + 1
print(new_s)
