Write a C++ function, bool ok(int q[]), which takes an array q and returns true if the array represents a valid configuration of the eight queens and returns false otherwise.

Please code in C.

Can you help me write a C++ program to do the following: Create a function append(v, a, n) that adds to the end of vector v a copy of all the elements of array a. For example, if v contains 1, 2, 3, and a contains 4, 5, 6, then v will end up containing 1, 2, 3, 4, 5,6. The argument n is the size of the array. The argument v is a vector ofintegers and a is an array of integers. Write a test driver

Write a function that takes in an array of integers and returns the integers that are either palindromes or almost-palindromes. An almost-palindrome is any integer that can be rearranged to form a palindrome. For example, the numbers 677 and 338 are both almost-palindromes, since they can be rearranged to form 767 and 383, respectively. Examples palindromeSieve ([443, 12, 639, 121, 3232]) [443, 121, 3232] // Since 443 => 434; 121 is a palindrome; 3232 => 2332 or 3223 palindromeSieve([5, 55, 6655, 8787]) → [5, 55, 6655, 8787] // Single-digit numbers are automatically palindromes. palindromeSieve ([897, 89, 23, 54, 6197, 53342]) - []
