One type of operation is to add some given number to each number in a given interval. The other are to ask for the sum of numbers in a given interval.InputThe first line contains the numbers N and Q. 1 ≤ N,Q ≤100000.The second line contains N numbers, the initial values of a1, a2, ..., an. -10

The array_sum () function returns the sum of all values in the array. If all values are integers, an integer is returned. If one or more of the values are floating-point numbers, the return value is floating-point numbers. Array_sum () definition and usageThe array_sum () function returns the sum of all values in the a
