math numbers

Instructions

Examples

howManyWalls(100, 4, 5) // 5
howManyWalls(10, 15, 12) // 0
howManyWalls(41, 3, 6) // 2

Notes

• Don’t count a wall if I don’t manage to finish painting all of it before I run out of paint.
• All walls will have the same dimensions.
• All numbers will be positive integers.

Solutions

function howManyWalls(n, w, h) {
	return Math.floor(n/(w*h));
}

TestCases

let Test = (function(){
    return {
        assertEquals:function(actual,expected){
            if(actual !== expected){
                let errorMsg = `actual is ${actual},${expected} is expected`;
                throw new Error(errorMsg);
            }
        },
        assertSimilar:function(actual,expected){
            if(actual.length != expected.length){
                throw new Error(`length is not equals, ${actual},${expected}`);
            }
            for(let a of actual){
                if(!expected.includes(a)){
                    throw new Error(`missing ${a}`);
                }
            }
        }
    }
})();
Test.assertEquals(howManyWalls(100, 4, 5), 5)
Test.assertEquals(howManyWalls(10, 15, 12), 0)
Test.assertEquals(howManyWalls(41, 3, 6), 2)
Test.assertEquals(howManyWalls(50, 11, 5), 0)
Test.assertEquals(howManyWalls(1, 1, 1), 1)
