1.take while loop in which u continue up to null in array of string.
2.once u get null pointer then take a new array of same length.
3.when u get null there ll save position no in variable i.
4.take while loop i to 0;
5.and j=0 for new array.
6.in above loop copy old array to new array in each cycle of loop.
7.j++;
8.u ll get reverse of string.
Reverse the string and compare it to the original. If they match, then it is a palindrome.
To reverse a number, first convert the number to a string, then reverse the string. Given your number consists of alphanumeric characters, the number must already be a string so simply reverse the string: #include<string> using std::string; string reverse (const string& s) { string str {}; for (auto c : s) str.insert (str.begin(), c); return str; } int main () { std::cout << "Enter a number: "; string s {}; std::cin >> s; std::cout << "The number in reverse is: " << reverse (s); }
//This function reverse any given string, except nullstatic string Reverse(string s) {char[] temp = s.ToCharArray();Array.Reverse(temp);return new string(temp);}//The main usagestring inputString = Console.ReadLine();Console.WriteLine(Reverse(inputString));
Use for loop declare string array str[] and string variable l= string length of string array j=l for i=0 to i=l/2 then temp=str[i] str[i]=str[j-1] str[j-1]=temp j=j-1 now print str array it will be reversed
The following codes only applied to unsigned integers: public int Reverse(int inputNumber) { string inputString = inputNumber.ToString(); string reversed = StringUtil.Reverse(inputString); return int.Parse(reversed); } public class StringUtil { // returns a reversed string from the given one public static string Reserve(string originalString) { StringBuilder sb = new StringBuilder(); char[] charArray = originalString.ToCharArray(); for (int i = charArray.Length - 1; i >= 0; i--) { sb.Append(charArray[i]); } return sb.ToString(); } }
Code example:/* ******************************************************************************** * FUNCTION: cpReverseStr ******************************************************************************** * DESCRIPTION: * Reverses a given string. Overwrites original. * * PARAMETERS: * cpString: The string to reverse. * * RETURNS: * Reversed string. ******************************************************************************** */ char * cpReverseStr( char *cpString) { register char cTmp; register char *cpFirst = cpString; register char *cpLast = cpFirst + strlen(cpString) - 1; while(cpFirst < cpLast) { cTmp = *cpFirst; *cpFirst = *cpLast; *cpLast = cTmp; cpFirst++; cpLast--; } return cpString; }
Yes, you can use regex to determine if a given string is a palindrome by reversing the string and then comparing it to the original string using regex.
write the javascript code to display the reverse no. of given no. (e.g. 247 reverse of 742)
there is no such method using string copy
C Code example:/* ******************************************************************************** * FUNCTION: cpReverseStr ******************************************************************************** * AUTHORS: * Flaun * * DESCRIPTION: * Reverses a given string. Overwrites original. * * PARAMETERS: * cpString: The string to reverse. * * RETURNS: * Reversed string. ******************************************************************************** */ char * cpReverseStr( char *cpString) { register char cTmp; register char *cpFirst = cpString; register char *cpLast = cpFirst + strlen(cpString) - 1; while(cpFirst < cpLast) { cTmp = *cpFirst; *cpFirst = *cpLast; *cpLast = cTmp; cpFirst++; cpLast--; } return cpString; }
Halv that given number,Make a square that has that half number as the length of a side.Stretch the string across the diagonal of the square from corner to corner.The length of the string is the square root of the given number
The violin is the highest pitched string instrument.
