同一個(gè)數(shù)會(huì)由于采用不同的基數(shù)而使得其表現(xiàn)的形式是完全不一樣的,在我們的學(xué)習(xí)中,我們熟悉的基數(shù)有10進(jìn)制、12進(jìn)制、60進(jìn)制、2進(jìn)制、8進(jìn)制和16進(jìn)制。比如數(shù)據(jù)12,如果我們用2進(jìn)制表示,則它就是1100;如果用3進(jìn)制表示就是110;如果用8進(jìn)制表示則是14。我們的編程任務(wù)就是與數(shù)的進(jìn)制(也就是基數(shù))有關(guān)。 程序中我們會(huì)給大家很多個(gè)數(shù)對(duì)(假設(shè)每個(gè)數(shù)對(duì)的數(shù)用X和Y表示),程序需要解決的問題就是為X和Y各選擇一個(gè)最小的基數(shù),以使得這兩個(gè)數(shù)在其選擇的基數(shù)上是一對(duì)相等的數(shù)。 例如,12和5這個(gè)數(shù)對(duì),我們可以為12選擇基數(shù)3,為5選擇基數(shù)6,這樣一來12(base 3)=5(base 6),因?yàn)?2(base 3)就是10進(jìn)制數(shù)5,而5(base 6)也是10進(jìn)制數(shù)中的5。 程序的輸入是通過文件完成的。 文件中的每一行都包含一個(gè)數(shù)對(duì)X和Y,兩個(gè)數(shù)通過一個(gè)或多個(gè)空格符分割,與X和Y相關(guān)聯(lián)的有效基數(shù)值范圍為2~36。X和Y的合理數(shù)值表示字符包括0—9和A-Z(表示數(shù)值10-35)。 文件的最后一行用一個(gè)數(shù)字0表示輸入的結(jié)束。

Problem Statement You are given a string input. You are to find the longest substring of input such that the reversal of the substring is also a substring of input. In case of a tie, return the string that occurs earliest in input. Definition Class: ReverseSubstring Method: findReversed Parameters: string Returns: string Method signature: string findReversed(string input) (be sure your method is public) Notes The substring and its reversal may overlap partially or completely. The entire original string is itself a valid substring (see example 4). Constraints input will contain between 1 and 50 characters, inclusive. Each character of input will be an uppercase letter ( A - Z ). Examples 0) "XBCDEFYWFEDCBZ" Returns: "BCDEF" We see that the reverse of BCDEF is FEDCB, which appears later in the string. 1)

This m file analyzes a coherent binary phase shift keyed(BPSK) and a amplitude shift keyed(ASK) communication system. The receiver uses a correlator(mixer-integrator[LPF]) configuration with BER measurements comparing measured and theoretical results. The bandpass and low pass used in the receiver are constructed using z transforms.
