Pictorial Presentation:

Sample Solution:
HTML Code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title> Check whether there is at least one element which occurs in two given sorted arrays of integers</title>
</head>
<body>
</body>
</html>
JavaScript Code:
function check_common_element(arra1, arra2) {
for (var i = 0; i < arra1.length; i++)
{
if (arra2.indexOf(arra1[i]) != -1)
return true;
}
return false;
}
console.log(check_common_element([1,2,3], [3,4,5]));
console.log(check_common_element([1,2,3], [5,6,7]));
Sample Output:
true false
Flowchart:

ES6 Version:

return true;
}
return false;

JavaScript: Tips of the Day
Converts a string to title case
Example:
const toTitleCase = str => str .match(/[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+/g) .map(x => x.charAt(0).toUpperCase() + x.slice(1)) .join(' '); console.log(toTitleCase('some_database_field_name')); // 'Some Database Field Name' console.log(toTitleCase('Some label that needs to be title-cased')); // 'Some Label That Needs To Be Title Cased' console.log(toTitleCase('some-package-name')); // 'Some Package Name' console.log(toTitleCase('some-mixed_string with spaces_underscores-and-hyphens')); // 'Some Mixed String With Spaces Underscores And Hyphens'
Output:
"Some Database Field Name" "Some Label That Needs To Be Title Cased" "Some Package Name" "Some Mixed String With Spaces Underscores And Hyphens"
