String Scramble


  1. CoderByte


Have the function StringScramble(str1,str2) take both parameters being passed and return the string true if a portion of str1 characters can be rearranged to match str2, otherwise return the string false. For example: if str1 is "rkqodlw" and str2 is "world" the output should return true. Punctuation and symbols will not be entered with the parameters.


Input: "cdore" & str2= "coder" Output: true

Input: "h3llko" & str2 = "hello" Output: false


function StringScramble(str1, str2) { // for each element of str2, remove the punctuation and symbols // this is more for robustness let filteredStr1 = str1.replace(/[^0-9a-zA-Z]/gi, ''); let filteredStr2 = str2.replace(/[^0-9a-zA-Z]/gi, ''); for (let i = 0; i < filteredStr2.length; i++) { // replace element if it exists in filteredStr1 if (filteredStr1.indexOf(filteredStr2[i]) === -1) { return false; } filteredStr1 = filteredStr1.replace(filteredStr2[i], ''); } return true; }
