rite and verify a program th odd integers. For example, when n is 4, the sum should be 1 + 9 is the specification: 25 + 49 - 84. Here Declarative interface: const int n; /* n is the number of squares (input) / int sum; /* the sum is stored in this variable */ Pre-condition: ASSERT ( n >- 1) The program should use a while-loop and standard arithmetic operations. Select a loop invariant and give a complete proof tableau for the program (including all the intermediate assertions). Also make an argument for termination
