To reverse a string "in place" without using a temporary string, use the reverse function template in the <algorithm> header: Demo Code#include <string> #include <iostream> using namespace std; int main() {// w w w . ja v a 2s .co m string s = "this is a test"; cout <<...
private int reverseNum(int num) { int rev = 0; while (num > 0) { rev = rev * 10 + num % 10; num /= 10; } return rev; } 10 最小公倍数 算法: a和b的最小公倍数 = a*b/a和b的最大公约数 性质: 如果a和b的最小公倍数是k,并且b和c的最小公倍数也是k,那么a和c的最小公...
algorithm: a temp to store previous node, pointing to that in iterator class ReverseList{ public List reverse(List l){ Node firstNode = l.getFirst(); Node temp = firstNode.next; firstNode.next = null; if(l == null || l.isEmpty) throw new NotValidException(); Node previousNode =...
Explanation: First, it calculates the sum of all elements in the array, similar to the sum - calculating methods above. Then, it divides the sum by the length of the array to get the average. The result is cast to adoubleto ensure precision in case the sum and length values result in...
To reverse a string A string can be reversed by using stack. The characters of string pushed on to the stack till the end of the string. The characters are popped and displays. Since the end character of string is pushed at the last, it will be printed first. ...
