【Edabit 算法 ★☆☆☆☆☆】Maximum Edge of a Triangle

algorithms math numbers

Instructions

Create a function that finds the maximum range of a triangle’s third edge, where the side lengths are all integers.

Examples

nextEdge(8, 10) // 17
nextEdge(5, 7) // 11
nextEdge(9, 2) // 10

Notes

• (side1 + side2) - 1 = maximum range of third edge.
• The side lengths of the triangle are positive integers.
• Don’t forget to return the result.

Solutions

function nextEdge(side1, side2) {return side1 + side2 - 1;
}

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}}}
})();Test.assertEquals(nextEdge(5, 4), 8)
Test.assertEquals(nextEdge(8, 3), 10)
Test.assertEquals(nextEdge(7, 9), 15)
Test.assertEquals(nextEdge(10, 4), 13)
Test.assertEquals(nextEdge(7, 2), 8)
