## Wipro Coding Test Pattern

Wipro Coding Questions is one of the important processes of Wipro off-campus and on-campus selections. Mainly 2 questions are asked in the exam in which 1st question is easy and the 2nd question is medium-difficult. Students have to code these two questions with the help of the given programming languages. The Languages which are supported are C, C++, Java, and Python. The time is given to the students to solve both the questions in only 60 minutes.

In this given period of time students have to solve one question completely or two questions with partial outputs. If most of the students have cleared all the two questions correctly then the final cut-off may vary or goes high.

**6. Gary is an avid hiker. He tracks his hikes meticulously, paying close attention to small details like topography. During his last hike, he took exactly n steps. For every step he took, he noted if it was an uphill or a downhill step. Gary’s hikes start and end at sea level. We define the following terms: 1. A mountain is a non-empty sequence of consecutive steps above sea level, starting with a step up from sea level and ending with a step down to sea level. 2. A valley is a non-empty sequence of consecutive steps below sea level, starting with a step down from sea level and ending with a step up to sea level. Given Gary’s sequence of up and down steps during his last hike, find and print the number of valleys he walked through?**

**Input:**

The 1’st line contains an integer, , denoting the number of steps in Gary’s hike. The 2’nd line contains a single string of characters. Each character belongs to {U, D} (where U indicates a step up and D indicates a step down), and the i(th) cin the string describes Gary’s i(th) step during the hike.
