Shortest Word Length Finder

Given a sentence containing several words separated by spaces, your task is to determine the length of the shortest word. Formally, if the sentence is represented as \(S = \{w_1, w_2, \ldots, w_n\}\), you must compute \(\min_{1 \leq i \leq n} |w_i|\), where \(|w_i|\) denotes the number of characters in word \(w_i\).

Input will consist of a single line containing the sentence. Your program should output a single integer corresponding to the length of the shortest word.

inputFormat
