//    Description:
//
// You are given an array including a list of basketball teams and their scores showing points scored vs points lost:
// .
// const basketballResults = [
//      ['Dallas Mavericks', '492:513'],
//      ['Los Angeles Lakers', '641:637'],
//      ['Houston Rockets', '494:458'],
//      ['Los Angeles Clippers', '382:422'],
//      ['New Orleans Pelicans', '433:454'],
//      ['Oklahoma City Thunder', '315:318'],
//      ['Golden State Warriors', '559:503'],
//      ['Memphis Grizzlies', '550:511'],
//      ['Portland Trail Blazers', '527:520'],
//      ['Minnesota Timberwolves', '495:494'],
//      ['Utah Jazz', '399:402'],
//      ['Sacramento Kings', '420:431'],
//      ['San Antonio Spurs', '469:460'],
//      ['Phoenix Suns', '523:522'],
//      ['Denver Nuggets', '646:658']
// ];
// .
// Your task it to return a number which represents the total number of points scored by a team from Los Angeles.
// .
// In the above example the correct result is a number of 1023, as Los Angeles Lakers got 641 and Los Angeles Clippers got 382, so 641 + 382 = 1023.
// .
// Notes:
// .
// The format of the Los Angeles team name will always start with 'Los Angeles' followed by one-word team name, for example, 'Los Angeles Name'.
// All letters will be in lower-case apart from first letters which will be in upper-case. Only letters will be used (no numbers, underscores, hyphens, special characters etc.)
// For example, the following strings do not represent a team from Los Angeles: 'Happy Los Angeles', 'Los Angeles', Los Angelesio Thunders', 'los angeles masters'.
// The number of teams from Los Angeles may vary.
// If there are no teams from Los Angeles, return the number 0.
// The order of the teams may vary.
// All values in the arrays will always be strings.
// Points will always be given in the following format '100:99' (points scored:points lost).
