    Python 3 solution

    Just counting how many times I hit the sea level climbing up.

    #!/bin/python3

import sys

def countingValleys(n, steps):
    seaLevel = valley = 0

    for step in steps:
        if step == 'U':
            seaLevel += 1
        else:
            seaLevel -= 1
        
        if step == 'U' and seaLevel == 0:
            valley += 1
    
    return valley
