Our football team finished the championship. The result of each match looks like “x:y”. Results of all matches are recorded in the collection.

## Solution to Total amount of points Question:

The simple solution to the ‘Total amount of points’ question is to first loop through the strings given in the games array, if the 0th index of games[i] > 2nd index of games[i] we have to add 3 to the score, else if they are equal we need to add 1 to the score. Finally, return the score value.

``````function points(games) {
let sum=0;
for (let i=0; i<games.length; ++i)
{
if (games[i]>games[i])
sum+=3;
if (games[i]==games[i])
sum+=1;
}
return sum;
}``````
``````//solution style 1 - easy to read and understand

function points(games) {
let result = [];
let score = 0;
games.forEach(x => {
result = x.split(":");
if(parseInt(result)>parseInt(result))
score += 3;
else if(result==result)
score += 1;
else
score += 0;
})
return score;
}``````
``````//solution style 2 - single line

const points=games=>games.reduce((output,current)=>{

return output += current>current ? 3 : current === current ? 1 : 0;  },0)``````
