  A Very Big Sum In this challenge, you are required to calculate and print the sum of the elements in an array, keeping in mind that some of those integers may be quite large. Function Description Complete the  aVeryBigSum  function in the editor below. It must return the sum of all array elements. aVeryBigSum has the following parameter(s): int ar[n] : an array of integers . Return long : the sum of all array elements Input Format The first line of the input consists of an integer  . The next line contains   space-separated integers contained in the array. Output Format Return the integer sum of the elements in the array. Constraints Sample Input 5 1000000001 1000000002 1000000003 1000000004 1000000005 Output 5000000015 Note: The range of the 32-bit integer is  . When we add several integer values, the resulting sum might exceed the above range. You might need to use long int C/C++/Java to store such sums. Solution: Language:  C 1 // Program to ...

    C PROGRAM TO CHECK PALINDROME ( string )   Palindrome:   A palindrome is a word, phrase, or sentence that reads the same in both backward and forward directions for example "level".  In other words,  A  string  is said to be a  palindrome  if the  string  read from left to right is equal to the  string  read from right to left. # include <stdio.h> # include <string.h> int main () {        int i, l, rev = 0 ;      char string[ 250 ];      printf ( "Enter a string: " );    scanf ( "%s", string );      l = strlen (string);      for ( i = 0 ; i < l; i++ ) {           if (string[i] != string[l-i- 1 ]){              rev = 1 ;                break;           }  ...
