Minimum increments to make all array elements equal with sum same as the given array after exactly one removal | Function to check if an array of equal elements with sum equal to the given array can be obtained or not ; Base case ; Stores sum of array elements ; Stores second largest array element ; Stores the largest array element ; Traverse the array ; Update secMax ; Update Max ; Update secMax ; Update totalSum ; If totalSum is less than secMax * ( N - 1 ) ) ; If totalSum is not divisible by ( N - 1 ) ; Driver Code
