一： int main() { char arr[50] = "We are happy."; int arrLen = strlen(arr); int blankNum = 0; for (int i=0;i<arrLen;i++) { if (arr[i] == ' ') blankNum++; } int len = arrLen + 2*blankNum;

class Solution {public: bool Find(int target, vector array) { int rowCount = array.size(); int colCount = array[0].size(); int i,j; for(int i=rowCount-1,j=0; i>=0&&j<colCount; ) { if(target == array[i
