Question

Write a function that would accept a string and checks if any character is repeated more than once. The function would return the repeated chars and the number of times they are repeated. The return value is a string, all pairs separated by a comma.

E.G. function(“2abc**zac22”); returns: 2=3,a=2,c=2,*=2

function getCounts(s){
    var values = [];
    var counts = [];
    for(var i = 0;i<s.length;i++){
        var f = 0;
        var j = 0;
        while(j<values.length){
            if(values[j]==s[i]){
                f = 1;
                break;
            }
            j++;
        }
        if(f == 0){
            values[values.length] = s[i];
            counts[counts.length] = 1;
        }
        else{
            counts[j] += 1;

        }
    }
    var result = "";
    for(var k = 0;k<values.length;k++){
        if(counts[k]>1){
            if(k == 0)
                result += (values[k]+"="+counts[k])
            else
                result += (","+values[k]+"="+counts[k])
        }
    }
   return result;
}
