How to make two strings anagram by removing characters in TypeScript

Answer 1

function RemoveCharactersNeedToBeRemovedForAnagram(str1 : string, str2 : string) {
    const TotalABCLetters = 26;
    let count1 : number[] = Array(TotalABCLetters).fill(0);
    let count2 : number[] = Array(TotalABCLetters).fill(0);
    const size1 : number = str1.length;
    const size2 : number = str2.length;
         
    // count char frequency str1
    for (let i : number = 0; i < size1; i++) {
        count1[str1.charAt(i).charCodeAt(0) - 'a'.charCodeAt(0)]++;
    }
         
    // count char frequency str2
    for (let i : number = 0; i < size2; i++) {
        count2[str2.charAt(i).charCodeAt(0) - 'a'.charCodeAt(0)]++;
    }
           
    for (let i : number = 0; i < TotalABCLetters; i++) {
        if (Math.abs(count1[i] - count2[i]) != 0) {
            str1 = str1.replace(String.fromCharCode(i + 97), ""); // 'a' = 97 ascii
            str2 = str2.replace(String.fromCharCode(i + 97), "");
        }
    }
     
    const arr = [str1, str2];
     
    return arr;
}
  
const str1 = "masterfx";
const str2 = "ksampret";
          
let [s1, s2] = RemoveCharactersNeedToBeRemovedForAnagram(str1, str2);
 
console.log(s1);
console.log(s2);
  
  
  
  
/*
run:
  
"master" 
"samret" 
  
*/
