python - Matching 2 short descriptions and returning a confidence level -


i have data banks using yodlee , corresponding transaction messages on mobile. both have description in them - short descriptions.

for example - 

string1 = "tatasky_tpsl mumba ind" string2 = "tatasky_tpsl"

they can matched if 1 inside other. however, strings like

string1 = "t.g.i friday's" string1 = "tgi friday's mumba mah"

still need matched. there y algorithm gives confidence level in matching 2 descriptions ?

you might want use normalized edit distance called levenstien distance levenstien distance wikipedia. after getting levenstien distance between 2 strings, can normalize dividing length of longest string (or average of 2 strings). normalised socre can act confidense. can find 4-5 python packages of calculating levenstien distance. can try online edit distance calculator

alternatively 1 simple solution algorithm called longest common subsequence, can used here

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
