When I am reversing a String using the recursive method it is giving me the stackOverflow Error.

public class ReverseString {    public static void main(String[] args) {        String str = "Juhi";        System.out.println(recursiveString(str));    }    static String recursiveString(String str) {             return !str.equals("") ? recursiveString(str.substring(1) + str.charAt(0)) : str;    }}

I did this program to reverse the order of the words in the give string. (And it works)

i.e. Output: sentence first the is This

However I am stuck when it comes to adding another sentence to the array.For example I need to have an array {"This is the first sentence", "And this is the second"} producing as output: sentence first the is This , second the is this And

int main() {    char str[] = {"This is the first sentence"};    int length = strlen(str);    // Traverse string from end    int i;    for (i = length - 1; i >= 0; i--) {        if (str[i] == ' ') {    // putting the NULL character at the position of space characters for     next iteration.        str[i] = '\0';        // Start from next character        printf("%s ", &(str[i]) + 1);        }}    // printing the last word    printf("%s", str);    return 0;}

I am new to C so its not surprising that I got stuck even if the solution is quite easy. Any help would be appreciated! Thanks!

Please help, I am new and I am trying to solve some online questions. I am stuck in a place.

How to print the first two letter of a string in reverse? For eg-

word = "abc"print(word[1:0:-1]) 

would return 'b' and not 'ba'

I need to reverse a given string in assembly 8086. I wrote a code that should work but I get the output

'MAGSM$HIMI

instead of

MAGSHIMIM

I can't figure out what is the problem with the code. I suspect the "$" is causing the problem but I have no idea.

My code:

 org 100hjmp main        chrs db  'M','I','M','I','H','S','G','A','M', '$'main:    mov bp, sp    mov ax,offset chrs    call print_ax_str     mov ax, offset chrs    push ax    push 9    call reverse    PRINTN ;new line    mov ax,offset chrs    call print_ax_str     jmp stopreverse proc    ; First save the old BP      push bp     ; Now establish new BP     mov bp, sp      ;make space for 2 local variables    sub sp, 4    mov dx, [bp+6]    mov bx, [bp+4] ;bx = 9    dec bx         ;bx = 8    add dx, bx ; dx = dx + 8        mov di, dx     mov SI, [bp+6]     mov cx, 4    L1:     mov dx, [si]        xchg ax, [di]      mov [si], ax    mov [di], dx     inc si        ;si--    dec di        ;di++    loop L1    mov sp, bp     ; Restore OLD BP     pop bp    retn 4 reverse endpstop:    mov ah, 0     int 16h     retinclude magshimim.inc

i wanna create a Reverse word function, and i tried:

def reversa(str):    j=len(str)    for i in str:        j -=1        print(str[j], end="")print(reversa("Apple"))

But it did not work.
