I am building an algorithm of my own that is supposed to return the longest word from a sentence with javascript. The custom algorithm is compiling but returning an incorrect string. Am trying to solve programming problems without plagiarising so please help....
logic
a) Form an array out of the sentence using .split(" ") function.
b) Define a variable index that will be used to store the index of the element with the largest length
c) Define a default string mystring that we will use for comparisons in the loop
d) Iterate through the array we formed in step while comparing each string at each index with our variable mystring, if the string at the specified position is larger than our mystring,we get the index of that string and store it in the index variable..
e) We return the string at the index of the array that we got from the loop
Expectations
For a sample sentence like I love the United States of America,the algorithm should return America as the longest string. Instead its returning United which is false.
The rest of the problem is commented in my code below
Code
function longestWord(sentence) {
//we use this index to store the index of the
//longest word in the array
let index = 0;
//define an empty string for comparison
let mystring = "";
//define a new array
let arr = sentence.split(" ");
//iterate through the array
for (let p = 0; p < arr.length; p++) {
if (arr[p].length > mystring.length) {
//get the index and store in the variable
index = p;
}
}
//return the element at the index we got
return arr[index];
}
console.log(longestWord("I love the United States of America"));
//function returns United, please helpyou forgot to change the mystring variable valut to the new string value.
try this :
function longestWord(sentence) {
//we use this index to store the index of the
//longest word in the array
let index = 0;
//define an empty string for comparison
let mystring = "";
//define a new array
let arr = sentence.split(" ");
//iterate through the array
for (let p = 0; p < arr.length; p++) {
if (arr[p].length > mystring.length) {
//get the index and store in the variable
index = p;
mystring=arr[index];
}
}
//return the element at the index we got
return arr[index];
}
console.log(longestWord("I love the United States of America"));
