Please modify the code of comparing two user entered strings so that it does not effect by case in Java

In Python3, write the code for a function mult_3 that returns a list of all non-negative multiples of 3 that are less than or equal to a given argument n.

*C Programming This exercise is to help you learn how to debug  compiler warnings/errors and other common errors in your code.   For each part labeled P(n), there is a warning/error/problem that goes with it.  Write down what the issue was in the `Error:` section of each problem.  Work on `segfault.c` along with your fixes and error comments.   segfault.c file   // P0#include <stdio.h>#include <stdlib.h>/* Error: */ void fib(int* A, int n); intmain(int argc, char *argv[]) {int buf[10];unsigned int i;char *str;char *printThisOne;char *word;int *integers;int foo;int *bar;char *someText; // P1for (i = 0; i <= 10; ++i) { buf[i] = i;}for (i = 0; i <= 10; ++i) { printf("Index %s = %s\n", i, buf[i]);}/* Error:  */ // P2str = malloc(sizeof(char) * 10);strcpy(str, "Something is wrong");printf("%s\n", printThisOne);/* Error:  */ // P3word = "Part 3";*(word + 4) = '-';printf("%s\n", word);/* Error:  */ // P4*(integers + 10) = 10;printf("Part 4: %d\n", *(integers +…
