Assume we are dealing with an environment which could only store integers within the 32-bit signed integer range: [−231, 231 − 1]. For the purpose of this problem, assume that your function returns 0 when the reversed integer overflows. 注意:假设我们的环境只能存储得下 32 位的有符号...
Problem Description: Your are given an array of positive integersnums. Count and print the number of (contiguous) subarrays where the product of all the elements in the subarray is less thank. 题解: 很快想到了two pointer的解法,但是一直被corner case困住。 两个典型的case [1,2,3] 0 这个情...
