The code by me:
process.stdin.resume();
process.stdin.setEncoding(‘utf8’);
// your code goes here
let input = ‘’;
let currentline = 0;
process.stdin.on(‘data’, _=> input+= _)
function readline(){
return input[currentline++]
}
process.stdin.on(‘end’, function(){
input = input.split(’\n’)
let testcases = Number(readline())
while(testcases–){
let noofworkers = Number(readline())
let salaries = readline().split(’ ').map(Number)
let nooftimes = 0;
let max = Math.max(…salaries)
nooftimes = salaries.reduce((sum, val)=> sum+(val), 0)
nooftimes = (salaries.length*max) - nooftimes
console.log(nooftimes)
}
})
please reply
