ProblemWrite a program to find the sum of perfect square elements in an array.Given a number of elements in array as input and the sum of all the perfect square of those elements present in the array is output.SolutionFor example, Input= 1, 2, 3, 4, 5, 9, 10, 11, 16 The perfect squares are 1, 4, 9, 16. Sum = 1 + 4 + 9 +16 = 30 Output: 30AlgorithmRefer an algorithm given below to add the perfect square elements in an array.Step 1 − Read number of elements in array at runtime.Step 2 − Input the elements.Step 3 − ...
