arr [] is the number of data columns, and that the string. if there are n number of save arr [0] to arr [n-1], and to ensure that each number is greater than 0 and less than ASCII. Before the call parameters set: arr [n] = 0, n++ This gives sa [] series: sa [0] is certainly equal to n, that is ranked 0 starts with the n-suffix string, this is our plus up, is useless. sa [1] before the real string# 1 (first) string starting position rank in arr [] [i] = j series: i-starts with the string rank j, we can see rank [n] = 0. height [i] = j indicates the ranking is a string of i, and in front of it a string (i.e., i-1) of the common prefix. Seen height [] the effective range of 2 ~ n height [1] is a ranking of 0 and ranked as one of the common prefix ranked 0 we add to the arr [n] = 0, all must be 0 and does not make sense
