text: Find the maximum possible value of the minimum value of modified array | Function to find the maximum possible value of the minimum value of the modified array ; To store minimum value of array ; To store sum of elements of array ; Solution is not possible ; zero is the possible value ; minimum possible value ; maximum possible value ; to store a required answer ; Binary Search ; If mid is possible then try to increase required answer ; If mid is not possible then decrease required answer ; Return required answer ; Driver Code
