text: Check if any anagram of a string is palindrome or not | Javascript program to Check if any anagram of a string is palindrome or not ; function to check whether characters of a string can form a palindrome ; Create a count array and initialize all values as 0 ; For each character in input strings , increment count in the corresponding count array ; Count odd occurring characters ; Return true if odd count is 0 or 1 , ; Driver program to test to print printDups
code: let NO_OF_CHARS = 256 ; function canFormPalindrome ( str ) { let count = new Array ( NO_OF_CHARS ) ; count . fill ( 0 ) ; for ( let i = 0 ; i < str . length ; i ++ ) count [ str [ i ] . charCodeAt ( ) ] ++ ; let odd = 0 ; for ( let i = 0 ; i < NO_OF_CHARS ; i ++ ) { if ( ( count [ i ] & 1 ) != 0 ) odd ++ ; if ( odd > 1 ) return false ; } return true ; } document . write ( canFormPalindrome ( " " ) ? " " + " " : " " + " " ) ; document . write ( canFormPalindrome ( " " ) ? " " : " " ) ;
