C. Good Subarrays (好题,前缀和优化技巧) 题意:给定好子数组的概念:若子数组的元素之和等于元素个数,那么这个子数组就为好子数组。那么给你一个子数组序列字符串,判断该序列有多少个好子数组。 题解:首先子数组元素之和等于元素个数,那么这句话就等价于元素个数等与子数组元素的和(废话),这就意味着我们...

C. Good Subarrays You are given an array ???1,???2,…,??? consisting of integers from 0 to 9. A subarray ???,???+1,???+2,…,???−1,??? is good if the sum of elements of this subarray is equal to the length of this subarray (∑???=???=???−???+1). For ...
Here, acircular arraymeans the end of the array connects to the beginning of the array. (Formally,C[i] = A[i]when0 <= i < A.length, andC[i+A.length] = C[i]wheni >= 0.) Also, a subarray may only include each element of the fixed bufferAat most once. (Formally, for a ...
Write a program in C to find the maximum product subarray in a given array. Expected Output : The given array is : -4 9 -7 0 -15 6 2 -3 The maximum product of a sub-array in the given array is: 540 To find the maximum product subarray in a given array, the program needs to...
