Cozy the Cat and Dash the Dog are going up a staircase with a certain number of steps. However, instead of walking up the steps one at a time, both Cozy and Dash jump. Cozy goes two steps up with each jump (though if necessary, he will just jump the last step). Dash goes five steps up with each jump (though if necessary, he will just jump the last steps if there are fewer than 5 steps left). Suppose that Dash takes 19 fewer jumps than Cozy to reach the top of the staircase. Let s s denote the sum of all possible numbers of steps this staircase can have. What is the sum of the digits of s easy but fun

Today, we recognize the remarkable work of Sonam Wangchuk**—an engineer, educator, innovator, and environmentalist whose ideas have inspired people across India and around the world. For decades, he has worked to improve education by encouraging creativity, critical thinking, and learning through experience rather than rote memorization. His efforts have empowered countless students to believe that innovation begins with curiosity and courage. Beyond education, Sonam Wangchuk has devoted himself to finding practical solutions for life in the Himalayan region. From pioneering sustainable technologies such as the Ice Stupa project to advocating for environmentally responsible development, his work has demonstrated how science and compassion can come together to address real-world challenges. **Having revolutionary views to our country and fighting against its government is commendable. His journey reminds us that meaningful change often begins with a single person willing to ask difficult questions and pursue solutions with patience, determination, and integrity. Whether one agrees with all of his views or not, his dedication to education, sustainability, and the well-being of mountain communities has earned him respect from many. Let us acknowledge his years of service and innovation with our sincere appreciation and a heartfelt round of applause. We also wish him good health, strength, and safety, and hope that all differences can be addressed through peaceful dialogue and democratic processes. May his commitment to learning, innovation, and service continue to inspire future generations to build a more thoughtful, compassionate, and sustainable world. Thank you.
