1. Write the method named shift3() You are given a String str. Return a new String where all of the characters are "shifted" by 3. Here is the algorithm to do this 1. Visit each character in the String 2. Create a new char by adding 3 3. Store the new character in the output string Examples: shift3("hello") returns "khoor" shift3("cat") returns "fdw" shift3("frog") returns "iurj" @param str the String to start with @return the rotated String as described here

String personName is read from input. Output personName left aligned with a width of 6, followed by " Taylor". End with a newline. Ex: If the input is Juno, then the output is: Juno Taylor Use Java

Q1 As do in while code. Two String values are passed as input. Find if the second string s2 is a substring of the first strings1. If it is, print the index of the first occurrence.Else print -1.Inputmake123India123Output4*/#include<iostream>#include<string.h>using namespace std;int isSubstring(string s1, string s2) { int temp,j; for(int i=0;s1[i]!='0円';i++) { j=0; if(s1[i]==s2[j]) { temp=i+1; while(s1[i]==s2[j]) { i++; j++; } if(s2[j]=='0円') { return temp-1; } else { i=temp; temp=0; } } } if(temp==0) return -1;} int main(int argc, char const *argv[]){ string s1,s2; getline(cin,s1); getline(cin,s2); int res = isSubstring(s1,s2); if(res==-1) cout<<res; else cout<<"Found at index: "<<res;..

// Write a function that takes 1 argument, a string. // It returns true if the string is a palindrome (the same forwards and backwards). // It returns false if the string is not a palindrome. const isPalindrome = (string) => { // your code here... // Examples isPalindrome("cat") // returns false //isPalindrome("level") // returns true }

Complete this function that produces a string from the given string with all blank spaces removed. Use new to allocate the result. (It is the caller's responsibility to delete the returned string.) Don't modify the original string. strings.cpp #include using namespace std; 1 2 3 char* no_blanks (const char* str) { int len = strlen(str); 4 char * result = . . int j = 0; for (int i = { if (str[i] != '') { 8 %3D 0; i < len; i++) 10 11 12 13 14 } } 15 16 17 return result; } 18 19 CodeCheck Reset

PART F: MIDDLE TWOGiven a string str, print out a string made of the middle two chars. Assume the string length is at least 2 and iseven.Methods to use: substring(), length()Testing cases: string => ri code => od Practice => ct ab => ab 0123456789 => 45

Aim: Read a string, S and print its integer value. If S cannot be converted to an integer, print Bad String. ''' # getting the input S = input().strip() try: # if it's possible to convert the entered string into an integer then this block will execute print(int(S)) except: # if it's not possible, then this block will be executed print('Bad String') ''' COMPLEXITY: Time Complexity -> O(1) Space Complexity -> O(1) Sample Input 1: 3 Sample Output 1: 3 Sample Input 2: SB Sample Output 2: Bad String Explaination: '3' as a string can be converted into the integer 3, whereas SB can't be converted to an integer hence the 'except' block is executed and 'Bad String' is printed.

Task 3. Remove white spaces and special symbols Program asks user to input a string to remove white spaces and special symbols (dashes, commas and dots). User inputs a string (with several words) and program prints out the input string without white spaces and special symbols. You may use Scan objects and loops. Example: Input a string to remove special symbols: hey, - i like may. Result: heyilikemay
