CODE THE FOLLOWING FUNCTIONS IN JAVASCRIPT (USE OF THE ABOVE MENTIONED IN BUILT FUNCTIONS IS NOT ALLOWED)

Write a function that accepts an array as argument. The function should loop through the array elements and accumulate the sum of ASCII value of each character in element and return the total. For example: function([‘A’, ‘bc’, 12]); // returns 361 which is the sum of 65 + 98 + 99 + 49 + 50


Write a function that accepts two arguments (a string array and a character). The function will check each string in an array and count the number of instances of the character that was passed as second argument, if it is placed in an odd index position in that string, regardless of case. The counts for each element of an array are concatenated as one string separated by hyphen and returned E.G. function([“AaA123Aa”, ”Hannah”, ”1090aambcaA”], “A”); // returns: ‘2-1-2’

Q1)

<script type="text/javascript">
   function sumOfAscii(arr) {
       //sum of ascii values
       sum=0;
       for(i=0;i<arr.length;i++){
           //converting the value at position to string value
           arr[i]=arr[i]+'';
           //traversing through each value in the position
           for(j=0;j<arr[i].length;j++){
               //charCodeAt() will return ascii value of the element
               sum+=arr[i].charCodeAt(j);
           }
       }
       //returning the sum
       return sum;
   }
   document.write(sumOfAscii(['A','bc',12]));
</script>

function sumofAscii(arr) { //sum of ascii values sum=0; for(i=0;i<arr.length;i++){ //converting the value at position to string value arr[i]=arr[i]+""; //traversing through each value in the position for(j=0; j<arr[i].length;j++){ //charCodeAt() will return ascii value of the element sum+=arr[i].charCodeAt(j); y } //returning the sum return sum; } document.write(sumofAscii(['A', 'bc',12]));

output:

361

Q2)

function fun(arr,char){
str="";//empty string to store count of char
//traversing through array
code=char.charCodeAt(0);
upper=lower=code;
if(code>=65 && code<=90){
upper=code;
lower=code+32;
}
else if(code>=97 && code<=122){
lower=code;
upper=code-32;
}
for(i=0;i<arr.length;i++){
c=0;//count of char in the string
for(j=0;j<arr[i].length;j++){
//in case of a odd index
//if the index value match with char
//count is incremented
if(j%2!=0)
if(arr[i].charCodeAt(j)==upper || arr[i].charCodeAt(j)==lower)
c++;
}
//concatnating count and '-'
if(i!=arr.length-1)
str+=c+"-";
else
str+=c;
}
//returning the string without last '-'
return str;
}
document.write(fun(["AaA123Aa", "Hannah", "1090aambcaA"], "A"));

<script type="text/javascript"> function fun(arr,char){ str="";//empty string to store count of char //traversing through array code=char.charCodeAt(0); upper-lower=code; if(code >=65 && code < =90){ upper-code; lower=code+32; 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 } else if(code >=97 && code< =122){ lower=code; upper-code-32; } for(i=0;i<arr.length; i++){ C=0;//count of char in the string for(j=0; j<arr[i].length;j++){ //in case of a odd index //if the index value match with char //count is incremented if(j%2!=0) if(arr[i].charCodeAt(j)==upper || arr[i].charCodeAt(j)=-lower) C++; } 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 //concatnating count and '-' if(i!=arr.length-1) str+=C+"-": else str+=c; } //returning the string without last '.' return str; } document.write(fun(["AaA123Aa", "Hannah", "1090aambcaA"], "A")); </script>

output:

2-1-2
