Solution

def getMax(operations):

stack = list()
sol = list()
max_number = [0]

for i in operations:
    if i[0]=='1':
        number = int(i[2:])
        stack.append(number)
        if number >= max_number[-1]:
            max_number.append(number)

    elif i[0]=='2' and stack:
        poppednumber = stack.pop()
        if poppednumber==max_number[-1]:
            max_number.pop()

    elif i[0]=='3':
        sol.append(max_number[-1])

return sol

Why programmer using C, uploaded code and did not use the fonction in the online editor on the site

**This is the code of javascript **

function getMax(operations) { const stack = []; // Initialize an empty stack const maxs = []; // To store maximum elements for type 3 queries

operations.forEach((op) => {
    if (op === '2') {
        // Delete the element present at the top of the stack
        stack.pop();
    } else if (op === '3') {
        // Print the maximum element in the stack
        const max = Math.max(...stack);
        maxs.push(max);
    } else {
        // Push the element x into the stack
        stack.push(Number(op.slice(2)));
    }
});

return maxs;

}

How is it possible that when I run code for a test case and it is successful, but when submit the code, the result for the same test case is unsuccessful?!!
