Problem:
Given a string and an int n, return a string made of the first n characters of the string, followed by the first n-1 characters of the string, and so on. You may assume that n is between 0 and the length of the string, inclusive (i.e. n >= 0 and n <= str.length()).
repeatFront("Chocolate", 4) → "ChocChoChC"
repeatFront("Chocolate", 3) → "ChoChC"
repeatFront("Ice Cream", 2) → "IcI"
Solution:
public String repeatFront(String str, int n) {
int len = str.length();
String newWord = "";
for (int i = n; n > 0; n--){
newWord += str.substring(0,n);
}
return newWord;
}
String result = "";
ReplyDeletefor( ; n >= 0; n-- ) {
result += str.substring(0, n);
}
return result;
String s="";
ReplyDeletefor(int i=0;i<n;)
{
s = s + str.substring(i,n);
n--;
}
return s;
String result = "";
ReplyDeletewhile (n > 0) {
result = result + str.substring(0,n);
n--;
}
return result;
public String repeatFront(String str, int n) {
ReplyDeleteString result="";

}

}

}
