How to console log pairs in array

February 18, 2022

For example I have this string "()[]|}" and I want to compare each characters with eachother, but first I can’t get the loop to work correctly. For the first log it works correctly, but after instead of going +1 it should go +2 I believe so it doesn’t start from ). How do can I do this properly?

function isValid(s) {
    
  let temp = s.split("");

  for (let i = 0; i < s.length/2; i++) {
        console.log(temp[i], temp[i+1]);
  }
};

isValid("()[]|}");

I want to log this

( )
[ ]
| }

not

( )
) [
[ ]

>Solution :

Your code is correct but your for loop is slightly off:

for (let i = 0; i < s.length; i += 2) {

Loop while i is less than the length, but add 2 instead of 1.

function isValid(s) {
    
  let temp = s.split("");

  for (let i = 0; i < s.length; i += 2) {
        console.log(temp[i], temp[i+1]);
  }
};

isValid("()[]|}");
