Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. Example 1: Input:121Output:true Example 2: Input:-121Output:falseExplanation:From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not ...
#include <iostream> using namespace std; int main() { int a,b,s=0; cout << "Hii. Enter a number: "; cin >> a; b=a; while(a!=0){ s=s*10+a%10; a/=10; } if(s==b) cout << "Palindrome."; else cout << "Not Palindrome." return 0; } 25th Mar 2021, 5:19 AM ...
Let us check if a number is a palindrome or not by using C++ program. Code: #include<iostream>usingnamespacestd;intmain(){intx,number,reverse=0,temp;cout<<"Please enter a number here: ";cin>>number;x=number;do{temp=number%10;reverse=(reverse*10)+temp;number=number/10;}while(number...

故直接用最原始的写法,从两端比较数字是不是相等 注意负数的情况,尽量少用pow,其时间开销比较大 #include <iostream> using namespace std; bool isPalindrome(int x){ if( x < 0) return false; int maxDiv = 1; while (x/maxDiv >= 10) maxDiv *=10; ...
